Types of fish

Of course, you need to think about the types of fish you want to keep. Various types of fish need different care, maintenance, conditions, space requirements and equipment. If you purchased your aquarium equipment before you have decided what type of fish you want to keep, you can have some problems in maintaining your aquarium.


Aquarium maintenance would involve your first task – research. It is very essential to learn a lot about the fish you want to keep. This will let you know what special considerations they will need, what equipment you will buy and how to set-up your aquarium. When you research about these things, you can establish how big they will get and in this manner you can figure out the size of the aquarium you will need to keep your fish happy and healthy. As well, this will provide you an opportunity to learn if the different types of fish care needs, size or behavior are too different; they will not be appropriate and suitable.


After studying general information about the fish, you should ponder on the size of the tank you need. Survey your home and determine a spot for your new home aquarium. How much space you can allow for your aquarium including the extra paraphernalia? Take note of the space between the tank and the wall for adequate room for other equipment such as water filters, tubes and pumps.


If you have money problems, is it time to purchase that $ 300 fiber glass fish tank? If you really want to puruse the hobby, you can buy cheaper aquarium at first, and if you have enough money, upgrade your fish tank. You can also slash the budget by finding stores that are selling second hand aquariums.


You should visit various pet stores near you and figure out what equipment are available and how much they cost. If you cannot find something that will help you for your pleasure, you can inquire about special orders. Make sure to ask for a price range or if possible a fixed price before you signs up for an order.

Budget-space constraints

How does your budget match up to the cost of the equipment you want? Can you purchase a larger aquarium enough for your fish that are suitable in the room available in your home? You should consider the budget and space limits, and then analyze your fish type, your space limits and your financial considerations compared to the new information you now have.

When you have evaluated these factors, you can purchase the equipment and the fish you want to keep. If you need to special order the equipment, you should do it immediately as it will take time for the order to arrive. Then, if everything is set, you are ready to pursue your hobby of aquarium keeping. Whether you just like to keep a couple of goldfish, or if you want to venture into tropical fish, these factors will help you to start on the right track.

Setting Up Your Home Aquarium: All About Fish Tanks

The aquarium tank is the most important equipment you should pick wisely in setting up your home aquarium. It is not something to be purchased in a hurry. The aquarium tank has to be appropriate for what you are thinking to keep. The tanks can be used to keep aquatic animals such as tropical fishes, mollusks, and even amphibians, if that’s what you prefer. All these pets need different aquarium types and various kinds of things inside the tank. Fish are the easiest pets to maintain while corals and amphibians are a lot more difficult than the other aquatic animals.

Keeping corals inside the aquarium tank is quite difficult. They need near-oceanic set up, that is, the water should mimic the salty environment of the ocean. It also needs to have enough sunlight, a salt ground of 0.7 – 0.8, this is the maximum intensity for fish and corals that lives in salty environment. Corals are delightful aquatic creatures, but they are quite differently tinted and also available for this kind of set up are sea anemones. Sea anemones are finger-like plants that waves with the sea current and are totally relaxing to see. Saltwater fish can also be added in a coral or sea anemone tank.

However, some sea anemones are harmful for some fishes because they can sting them.

As previously stated, fish are the easiest to maintain in an aquarium, they just need healthy water and food. They also need a water filter, a water conditioner and proper lighting (not direct sunlight). There are numerous kinds of fish that can be maintained in a home aquarium and they all need various kinds of environment, so check that your home aquarium is appropriate for the type of fish that you have.

Aquarium tanks, obviously, is the most important part of an aquarium set-up, you have to check that the tank is appropriate for the kind of creature you want to maintain, or else they will die in just a few days. Some aquarium tanks of good quality are quite expensive, because they are composed of fortified and safety fiber glass that hardly breaks when you fill it with full tank water.

You can also check for aquarium cabinets, which usually come with expensive aquarium tanks when you buy them from fish store. The size of the aquarium depends on the cabinet. Some aquarium cabinets work as support beams for the tank. The cabinets usually come with a storage area under the place where the aquarium is placed. This is a good spot for you to keep your materials that you are not yet using such as extra filters, pebbles, and also spare food.

Cabinets come in various sizes and designs or they can be specially built or you can contract a manufacturer to make it more personalized. Custom built aquarium cabinets are quite costly even though you will have what you really want. Ready to use cabinets are available in different features. They are crafted to endure the different weights of tans so you can always purchase ready to use aquarium cabinets normally up to about 5-7 feet long and they are normally available in wood shades such as maple or black. Some cabinets are also pastel colored for more vibrant decoration.

Setting Up Saltwater Home Aquarium from Freshwater Aquarium

Are you thinking of converting your fresh water aquarium to a saltwater kind? There are many aquarists that have done this, but they were unsure at first as to how much components and equipment can be used for the transformation. With some exceptions, most of your equipment can be used for this reason. That being discussed, you can do the conversion by tackling each piece of equipment.

The Aquarium

Most aquariums are not specially customized for freshwater or saltwater. The material used such as glass can be used for both type of aquarium, but they have their own advantages and disadvantages. As far as the size of the tank, saltwater aquarium has the tendency to be quite bigger, though the reef aquariums are very popular nowadays. A freshwater aquarium even as small as 10 gallons can be transformed into a saltwater aquarium, but you should take note that smaller aquariums are rather sensitive and intolerant to work with, and most of aqua culturists prefer the 55 gallon aquarium.

Filters and Filtration Systems

The filtration system in a saltwater aquarium is quite more elaborate than in the freshwater. Because water filtration is the spine of a saltwater system, the filter choice is unquestionably the most essential part of the saltwater set up process. In all possibility, the filter system you are currently using will need to be replaced. The little grasp-on-tank biological cycle and box, or in-tank corner kind filters usually used in freshwater aquariums are normally not great in saltwater aquariums. The conventional pebble set-ups, though still employed by most saltwater aqua culturists, adds to unnecessary nitrate problems as the aquarium grows, and they have lost their availability as more high-tech filtration systems such as the wet-dry trickle and flask kind filters with biological channel chambers have been introduced.

As far as the kind of filtration system you use, there are no specific rules. Every aqua culturist has their own preference as to what kind of set-up is best, but the easiest method to determine what you really need for your saltwater aquarium varies over is to decide on whether you want a fish or a reef aquarium system. You should also study the different filtration methods and filter set-ups that you need to choose from, and then pick one that is based on what you like. It is not usually harmful to start with a filtration system that can be employed for a reef aquarium. In this manner, in the future if you decide you want to develop into the saltwater system, you can slash a few bucks by not having to buy a whole brand new system.

Pumps and Power heads

Most pumps and power heads employed in freshwater aquariums can be used in a saltwater set up with no hassles, as long as they are guaranteed safe to use in saltwater. Generally, saltwater tanks employ more water pumps and power heads to achieve higher water current and circulation, and specifically with reef aquariums they help in the expansion and over-all well-being of the corals.


The most common kind of freshwater aquarium substrate employed is those made of pebbles or gravel materials, and goes hand in hand with a wide range of colors and shape. It is very ornamental, and does not serve as water filter base just as the substrate does in a saltwater aquarium. However, this kind of substrate is not that great for use in a saltwater aquarium.

Setting Up Aquarium Lights

Any aquarium needs light for your fish to live; this doesn’t matter if it is a saltwater or a freshwater aquarium. There are however, various kinds of lights available for each one. Many fish need different lighting conditions. If you are not certain, you can ask the personnel from a fish store.

The best lighting is fluorescent bulb for vividly colored fish that gives the delight of bold colors and a pleasant effect in the aquarium that makes the fish stand out even more. Most aquarium lights are available in various sizes that suit your tank, as there are different sizes that could go well with your tank, However, some tank do not come with installed lights to the tank hood. You need to buy them separately. This could be costly since you also need to purchase the additional accessories for the lights.

Salt water aquarium or marine tanks need a different kind of lighting. The corals and anemones in a marine tank need a lot of intense light. Thus, you need to purchase a bigger kind of bulb. Coral reefs and sea anemones are very sensitive to light, and it’s their sure way to survive the artificial environment inside the tank.

You can find most kinds of aquarium lighting at pet shops. They are easy to find but they are very costly. So, if you can find cheaper ones but with good quality, go for it. You can also look for used aquarium lights but check first if they are still in good condition before you purchase them.

Your purpose in lighting your aquarium is to mimic the natural environment of the creatures in the fish tank. The most important thing to consider is the natural cycle. It sounds simple, but most starting aquarium keepers cannot understand the importance of this. You would be satiated and feel ill if you will live under intense lights or no light at all for 24 hours a day, for a long period of time. Extreme levels of lightning can cause anxiety to fish and other organisms inside the fish tank. It can also cause certain illnesses, and intervention in the natural process of their living. Since the day/night cycle will occur minimally inside your house, you need to mimic them.

Lightning not appropriate for fish tanks do not have the required wavelengths of the light spectra normal during daylight, that is very important for the health of your pets. Very high wavelengths, on the other hand, can promote algal bloom or excessive algae growth in the aquarium causing reduction of oxygen inside the tank. Situating your aquarium under direct sunlight seems a plausible solution, however, it can cause excessive warmth, boosted algal growth and a number of related problems. Thus, you need to devise lighting just for your fish tank, if you don’t have a hood with lights.

Aquarium light is also important to define and emphasize your fish tank. If your lights are lousy and dull, then do not look ahead to an extremely stunning aquarium, however if you would invest with that high quality and delightful lights then you are sure to have an aquarium that is breathtaking. You can choose from different colors so do not just stick with white bulbs. There are pastel bulbs in shades of pink, blue, green etc. You should use your creativity and preference to decorate your aquarium.

Set Up Your New Home Aquarium

Perhaps you have received a new aquarium as a holiday present, or would like to set-up a fish tank to add delight to your home or office. You may like to set up a fish tank for your kids, or even for yourself. There are various reasons that most people like keeping an aquarium, and as any tropical fish enthusiast, it can be a relaxing and satisfying hobby.

People like the idea of keeping a fish tank in their home, but are quite disheartened when the fish they keep suddenly die. Persistence and concern for the fishes are necessary when you are maintaining an aquarium. Setting it up appropriately from the start will establish if your fish tank can become a domestic fixture, or ends up gathering dust in the basement.


Picking the right spot to place your new fish tank is important. The fish tank should be away from open windows, as too much sunlight can cause algal bloom that can decrease the oxygen in the aquarium.

Place the aquarium away from air vents and direct heat. High temperature in the aquarium can happen if it is too close to an open air vent, causing some diseases to your fishes.

Check that the aquarium is on an even ground, since an uneven fixture in a fish tank is a blot on the interior. Larger aquariums must be situated near sturdy beams. At least one gallon of water weighs about 9 lbs, so a 50 gallon fish tank can weigh about 500 lbs., larger aquariums with this mass can cause your floor to droop, and even shatter through below.

A aquarium should have a running water filter for a few days before you add the fishes. This will make sure that the water has enough supply of oxygen. New fish tanks often get murky within the first days, and having a water filter is great to clean up the mess.

Water conditioners are also great for new aquariums. Most water utilities infuse chlorine to faucet water, which is not good for the health of your fishes, and will not dispose no matter how long the water is stored. Water conditioners will dispel the chlorine and other heavy metals from the water. But before using any chemical on the water, always read the label and instruction for using to be very sure.

Adding pebbles to the fish tank will not make it only delightful, but it also helps to make a healthy environment to healthy bacteria. An aquarium should have at least a few inches of pebbles. When you are looking for pebbles, you should remember that one pound of pebbles is good for every gallon of water. That is, a 50 gallon aquarium needs at least 50 lbs of pebbles.

Adding Fish

The largest blunder beginners make when adding fishes to an aquarium is adding too many at the same time. You should begin with two fishes. After two to three weeks, and after checking the water to make sure the water is healthy, you can add more fish. If you are not sure if the water is healthy, you can ask from the local pet store. They often charge a small price, but some stores do this for free.

If you add new fishes to the aquarium, a water filtration supplement must be infused. These filtration supplements are composed of healthy bacteria that dispel waste products, making the fish tank healthy for your fishes. There are fairly a number of these supplements in the pet store, and if you are not sure about which one is the right type for your needs, ask a personnel from the pet store, or better yet, a veterinarian.

How to Set-Up Your New Home Aquarium

For the simplest fish tank, you can buy a fifteen or twenty gallon glass aquarium with an air steered beneath a pebble filter, and a plastic hood with a pastel fluorescent light. The rule of thumb for pebbles is one pound per gallon of water. An air pump and water filter are also important. To slash a few bucks from your budget for an aquarium, you should purchase fluorescent light instead of incandescent bulb. Though fluorescent lights would cost extra bucks when you purchase them, incandescent bulbs consume more electric power. Alternatively, if you have enough money, you can purchase a power head instead of an air pump and substitute the hanging tank heater with a submersible type.

For amateurs, you can pick ornamental plants and artificial, resin, ceramic decorations that you can find in most pet stores. Most of these pet stores will have arrangements quite similar to this setup at a discounted price but normally the ornamental decorations should be purchased separately. You will also need a base to support the mass of the aquarium about 10 pounds each gallon of aquarium capacity. Bigger tanks are much less effort than smaller aquariums since they can keep more fish, support appropriate water conditions and will basically lead to a much more delightful experience with the home aquarium. Smaller aquariums will need a great deal of keeping and maintenance and more intensive care to keep the water healthy and your fish satisfied.

Setting up your home aquarium is very easy, when you have high quality equipment. You should take the base and place it in a spot of your home where you can enjoy it most, and where it will be easier to take care of it. You should place it somewhere where it will look pleasant, since it will not be an easy work to relocate the tank, and you should locate the aquarium away from direct sunlight and heat such as radiators.

Situate the aquarium on the base and be sure that there is strong placement between the tank and the base. Deformed surfaces can shatter the bottom of the tank. Make sure that the type of water filter you have purchased can filter at the bottom, you will need to deal with the filter first. The water filter should be located at the bottom of the aquarium. Situate the lift tubing in their sockets. For smaller aquariums tanks, one tube is enough if you are using a power head to run the water filter. If you purchased an air pump to steer the filter, you need to have two pumps. Read carefully the instructions on the water filter container to make sure that you have done everything when setting up the water filter such as plugging idle lift tube sockets or attaching bubble linings.

Before you place the pebbles and gravels, wash them thoroughly to rinse out unnecessary dirt and dust. Place the pebbles evenly. The lowest point of the pebbles should be near in the front of the aquarium so the accumulated slits will gather there, where you can see it when the aquarium needs cleaning. Be sure that the pebbles does not have many dips in it as it inclines to the back of the tank, to make your cleaning easier and more efficient.

How to Set Up Saltwater Home Aquarium

If you are thinking of putting up a salt water aquarium, maybe you have heard from other enthusiasts that it is difficult. In the past, saltwater aquarium is a very hard task. However, starting a saltwater aquarium is not actually a lengthy list of complicated tasks to do. Primarily, it will be wasting time, but it is satisfying and worthwhile. You should feel free to take your time and satisfy the whole delightful experience. A well set up and maintained aquarium is truly pleasant. There is nothing like sitting on your couch while watching fish play around the pebbles instead of viewing the late night news. When its frosty outside and that the air is so cold and chilly that your tears turns into ice crystals before it falls in the ground, it is very relaxing to stare into your tank and imagine yourself diving through the soothing waters of Hawaii, gazing the underwater world beyond your belief.

To put up your saltwater aquarium, you should determine a spot where you can place it. Though seems impossible, it is a big disappointment to relocate a 100 pound aquarium even for a few meters. You should be sure that the place is away from direct sunlight and heat, particularly during summer. You will possibly like to situate the aquarium where it can be easily noticed and satisfied, probably in the sitting area of your home. Most people set up their aquarium as the highlight of their living room, instead of the TV. Some enthusiasts are worried about the consequence of the weight of the aquarium to the floor structure. Still a bigger aquarium weighs about the same as two adults. Thus, if your floor structure can be shattered by the weight, you can place the aquarium against an outer wall, which is the sturdiest part of the floor. The next thing you have to do is to measure the spot for the aquarium. You should take note that you need enough space around the aquarium for maintenance and for the extra equipment.

Then, you should purchase the aquarium and other equipment. Bring your measurement notes with you and ylook for something that will be suitable to your space. Do not make a haste decision at the first pet store. Visit many stores as you can to watch out for promos or special offers and to compare the prices before you make your final purchase. Basically, saltwater fish needs a larger aquarium about 55 gallons up.

Most people have the misconception that it would take at least six weeks to cycle or maintain the water filter for a new saltwater aquarium. The basic method used for cycling an aquarium of putting a couple of fish in the new aquarium then waiting up for the cycle period of six weeks for the beneficial bacteria to grow. However, there are modern methods you can choose from to cycle saltwater aquarium such as adding sand, rocks or chemical bacterial additives.

In the past, most people also believed that water changes are the only method to decrease the nitrates which are harmful to the fish. However, recent developments in marine biology have developed other methods such as using denitrator machine, algal additives, nitrate absorbents and other filtration systems like Berlin and Jaubert.

Step by Step Tips before Setting up Your Home Aquarium

Finally, after a long search of what kind of pet to have for your home, you ended up with fishes instead of the usual dog and cat tradition. Before you can proceed on setting up your home aquarium for your new pet, let’s list down the step by step stuffs that you need to know before getting started with fish keeping.

• The very first task that you have to consider is determining the kind of fish that you would want to keep.
Just like the usual saying, there are a million types of fish in the ocean, deciding which to keep for your home can be quite tricky. Each variety of fish requires vital care depending on the conditions of the space, equipments to use and many other significant things necessary for the fish to survive on your fish tank.

• Researching about how to take care and the compatibilities of your prospected type of fish in and for your home should then be your next step to do.
Learning about the fish that you’ve decided to keep is a very important thing to consider in this new found hobby of yours. Thus, your first purchase shouldn’t necessarily concern any equipment yet, but rather, a book – that contains as much information as you need to know about your pet fish. This should give you more than just an idea of the type of conditions that would help your fish survive, as well as how big your fish tank should be, and what equipments you will need to purchase. Although you’re only starting with one fish, you should also try and research what type of other fishes are compatible with your chosen one. This will help keep your fish happy and healthy, even if you decide to add some more in the future.

• Determine and evaluate your space and budget constraints.
After your research, you should now know the size of the tank that you need for your fish. The next thing that you should do is look around your house and analyze whether it would fit on the spot where you were planning to put the tank the first time you thought about getting a pet fish. If it doesn’t, find a better spot. The idea here is to see if you have enough space within your home or the room where your aquarium will fit perfectly. When measuring the desired place where you want to put your fish’s aquarium, take into account the needed space between the wall and the tank for the filters, tubing and cords.
Once you’ve figured out the space and all that, your next step is to evaluate whether your budget sticks up to what you now need, and whether you still have enough for the rest of your fish tank’s needs.

• Select, purchase, and setup the equipments.
Visit your local pet store and check the availability of the list of equipments required for your aquarium. Check how much it costs. Consider the space you have reserved at home, and determine if everything you need is there. If an item is not available, ask if you can place an order for it, or check the other pet stores around your place.
When you’ve checked everything, and your budget permits, you can now proceed on purchasing the equipments that you need. Back at home, you can now spend time setting up your very first home aquarium. When it’s up, fill it with water and let it settle for a few days just to make sure everything that you have in your tank are working properly. No leaks, whatsoever.

• Select a starter fish and cycle your tank.
Purchase a starter fish that is inexpensive, relatively small, and should be something that you would want to keep in the long run. The starter fish is what you’ll use to help with the cycle of your tank for 4-8 weeks. The said 4-8 weeks is the cycling process of your tank on which you should be very diligent with the tank maintenance. Remember not to add any more fish during this span.
Once the cycle is complete, you are now ready to venture on the exciting world of fish keeping. The last step on the list is simply to maintain your aquarium’s condition at its best, and care for your pet fish or fishes if you decide to add some more healthy and happy.

Easy Corals for Your New Reef Home Aquarium

Most beginning aquarium hobbyists are a bit doubtful when starting a reef aquarium with marine corals. Their needs not being very well generalized, corals are used to be almost very impossible to keep from any period of time in a home aquarium. With recent developments, the information, products are now available so that corals can be successfully maintained in a home aquarium. Most “home” corals are called easy as such they are easy to care for. Your home aquarium can be devoted to corals alone, but it could be more pleasant to add a few fish and other organisms to have a biological setup.

Here are some “easy” corals.

Button Polyps

Also known as Sea Mat, this type of corals like bright light, but are lenient with low light. Thriving medium to strong wave current, Button Polyps have a high procreation level and are very aggressive. Most aqua culturists, keep these corals during the cycle period.

Finger Leather

Also known as Colt, this type of coral are great for new reef aquarium. While they are pliable to most light and wave conditions, these spectacular corals like medium light and wave current.

Sea Mushroom

Sea mushroom do not respond to bright lights or strong wave currents, to permit highest growth and procreation, these corals are best maintained under lower lighting conditions such as pastel fluorescent lights, and with slow water currents. These corals are also very safe for most organisms but they are harmful to soft and rocky corals since they have harmful effects on most of them.


This type of corals is also known as Leather, Mushroom Leather and Trough Coral. There are great for new aquariums that fit well to most lighting designs and low to medium wave currents. These corals grow fast and are known great for procreation.

Brain Corals

Brain corals are also known as Closed Brain Coral, Meat Coral and Pacific Cactus. These corals are very great in artificial environment, but they thrive in bright, indirect light, and slow to medium wave currents. These corals are tolerant to the presence of some stony corals such as Litphyton and are very rash to aquatic planktons.

Open Brain Corals

Open Brain Corals are also known as Lobed Brain Coral, Flat Brain Coral, Modern Meat Coral and Flower Coral. These type of corals do great with bright lighting and slow wave currents, however if simply enough light and water current is provided, it will expand well in an aquarium. The Open Brain Coral feeds nocturnally, however the tentacles seldom extend during the day and readily take planktons. They are not usually active however there have been experimental results of sweep tentacles at growth when they are near with other species of corals.

Green Star Polyps

Also known as Daisy Polyps, this type of corals are bearable of both extreme level of lightings as well as wave currents. Being receptive to iodine and aluminum oxide that are found in some phosphate eliminating sponges, care should be taken when adding these polyps to your reef aquarium.


Similar to button polyps, these corals also prefer bright lightings but can bear low lights and like moderate to strong wave currents, making them a good addition to new reef aquariums. These active corals have a high procreation rate and can be spread fast inside an aquarium.

Common Mistakes in Setting Up New Home Aquarium

No matter what type of aquarium hobbyist you are, here are the most common mistakes you can commit when you are about to set-up your new home aquarium. These mistakes can be prevented if you have enough knowledge.

Over feeding

Unconsumed fish flakes and other food particles are accumulated at the bottom of the tank, producing nitrates thus overloading the water filter.

Without the full understanding and knowledge of the nutritional needs of your fish, there is the tendency to feed your fish to satisfy their needs. If they are not eating the food you have sprinkled, most people will add more food, with the notion that the fish are not noticing them. You should feed the fishes twice per day. However, there are fishes that need special feeding requirements, so it will be safe to check first. You should also know what are the components of the food you are giving your fish by contrasting the nutrients in the market foods.

Haste Moving

Patience, aside from being a “virtue,” is a requirement with setting up your home aquarium. Too many people have committed the mistake of doing things fast and as a result, they have encountered certain problems. It is better to study first the things you need to know about the aquarium set up you are planning and carefully strategize your tasks.

Overloading the aquarium

A conflict that comes with moving in haste is stuffing too much fish and things into the aquarium all at the same time, particularly in an aquarium that is not yet totally cycled, or has just completed the biological cycle. Even in a properly set-up aquarium, placing too much “residents” can cause a problem called “new tank syndrome,” wherein the fish and other organisms are satiated with the new environment. You should do things slowly but surely. Home aquariums, particularly saltwater aquariums are not an urgent task, so take it easy pal.

Insufficient Filtration and Circulation System

Having enough water filtration is very important to successfully maintain an aquarium. There are different methods of filtration systems you can use, but not using the correct filter choice for the biological capacity designed for your aquarium can cause some problems. It is better to have more filtration system than being insufficient.

This same method applies to water circulation in the fish tank. Insufficient water flow all throughout the system can cause some problems with oxygenation that accumulates slime or other kinds of unnecessary things inside the aquarium. To solve this slimy problem, you can add a power head or a surge device.

Buying Animals without Having Enough Information about Them

It never stops to amaze us how we select new residents for our aquarium without having enough information such as what they are, and how to take care and feed them. Before you buy anything from the pet store, you should take some time to do research. You should not purchase on sudden impulse because you like the colorful fins of a tropical fish, how funny it looks, or for other reasons.

Animal incompatibility

Problems such as my lion fish ate my baby gold fish, my janitor fish won’t get along with the fighting fish, and similar situations are very frequent. Buying animals without having enough information about their social behavior can lead to injury or worse, fatality.
