What is a fish tank?
A fish tank is an aquarium that contains one or more freshwater or saltwater fish, or animals of various species, and plants. The size of the fish tank varies depending on the type of fish kept in it and its purpose (e.g., hobby, profit), but most range from to . Fish tanks are usually found within public homes and private businesses such as restaurants, pet shops, schools etc. They can also be put inside miniature golf courses for decorative purposes. A typical tropical fish tank has a capacity ranging from , while larger non-tropical tanks can reach capacities up to .
A biodome or biotope is another special feature made to accommodate specific types of live exhibits in zoos and aquaria. They mimic the natural environment of living things in their native habitat. Biotope aquariums are enclosed systems where the fish, invertebrates, plants, and equipment all require maintenance in order to ensure proper operation.
Aquariums range from the small freshwater glass box or bowl used primarily as a decorative item, usually kept on a desk or in a window sill; to large custom-made (and sometimes custom-contrived) tanks held in public displays at zoos or aquatic theme parks: the largest known aquarium to date was an estimated 2,500 cubic metres (88,000 US gal), which featured interactive exhibits including dolphins, sharks and rays. The world’s second largest freshwater aquarium is at the Oceans in Coorparoo, Brisbane.
How to take care of your fish and their environment
Once you have chosen the fish tank for your home or place of work, it is important to maintain it in good condition. Remember that fish need oxygen and clean water to survive so you will need to check these things on a regular basis.
– Make sure that all the plants and decorations are securely fastened to the side of the tank. Driftwood and ceramic pots look best when suspended from above rather than lying flat on the bottom of the tank. To secure plants and decorations use aquarium silicone sealant which will not harm any sea life, if used correctly. Check at least twice a week for leaks in seals around electrical equipment such as heaters or pumps, cracks in rocks and plants or anywhere else water may be entering into tank .
– Change out 20 percent of the water and vacuum the gravel once a week if you have an aquarium that is 10 gallons or less. Tank water should be replaced every three to four weeks in larger tanks. Water conditioner may be necessary when changing wet/dry filters on established fish tanks. – Dechlorinate tap water before adding it to an aquarium.
First fill a bucket with tap water and add some drops of chlorine/chloramine remover or leave the water to stand for at least half an hour. The amount of dechlorinator you need depends on the volume of water, but in general it is 1ml per 10 litres (2.64 US gal) for each cupful added to tank . – Keep your aquarium away from direct sunlight and do not place near heat sources such as radiators, fireplaces etc., which cause fluctuations in temperature. Light can also harm fish if it shines directly into their eyes, so try to position lighting fittings carefully. Make sure that there are no holes either in your ceiling or walls where strong light from another room may fall directly on smaller tanks.
Types of fish tanks available:
1/ Under gravel filter, this technology is used for freshwater aquariums with a small volume. The substrate is made up of fine particles like pebbles or crushed coral to a depth of approximately 1 inch (2.5cm). A thin layer (4-6mm) of sand or gravel is placed on top and the water is pumped by means of an external pump through the gaps in the gravel into an undergravel filter which contains ceramic rings linked together by hoses that have holes in them.
Water flows through these holes providing a large surface area for bacteria to grow and remove toxic ammonia and nitrite from the water which then settles at the bottom as sludge. The water then percolates back into the aquarium where it is cleaned by plants or other types of biological filter media before being re-circulated for use in the tank again.
The gravel acts as a barrier to prevent the fish from being poisoned and provides a home for invertebrates like snails, which are very useful at removing any algae that grows on the sides and bottom of tanks. Undergravel filters need regular cleaning because they tend to clog with fine particles in the substrate surrounding them, whilst their ceramic rings will eventually become damaged by excessive wear and tear. They should be dismantled regularly (about once every six months) cleaned thoroughly with hot water, dried out salt free aquarium cleaner and then reassembled.
2/ Canister filter, this type of filter works in a similar way to the undergravel filter and they are used for both freshwater and marine tanks. In addition to the ceramic rings, there is also a foam insert that should be cleaned at least once every month. The dirty water passes from the tank into a canister where it comes into contact with activated carbon granules which absorb any unpleasant odours or discolouration (such as yellowing caused by excess tannins in blackwater).
Large amounts of air are injected into the system through an air hose before passing through a bio-media such as Purigen® which is capable of removing ammonia, nitrites and nitrates from aquariums while cycling new aquariums. There may also be an additional carbon/phosphate phase reactor and another bio-media insert made from ceramic rings which is designed to remove phosphates.
Biological filtration takes place in the canister’s body media (or sponges) where bacteria colonise on all surfaces including sand or gravel that are kept wet by means of an external pump . Alternatively they can be used without heaters or chillers to create a tropical environment for cold water species such as Discus fish. Once a month, clean out any wetted filters with hot water, salt free aquarium cleaner and replace with fresh filter material if needed.
3/ Wet / dry filter this type of technology combines mechanical and biological filtration in one system. Most often it is integrated into the back of an aquarium and is made of acrylic. Water is drawn into the filter though a spray bar, which creates a current inside to suspend particles that are removed by mechanical filtration.
This technology is used for both marine and freshwater systems but it works differently for each one. In marine tanks, bacteria colonise on the surface of live rock now submerged in the aquarium while there will be ceramic rings above this area where water is pumped through as before. However, instead of just passing through gravel or sand, water also passes over porous ceramic media that has been filled with other types of biological media like activated carbon granules which absorb odours and discolouration caused by excess tannins (yellowing).
The best types of aquariums for different needs .
There are many different types of fish tanks available and each one is designed for a specific use. The first consideration when choosing which type of tank to purchase should be the volume (cubic feet) of water that it holds because this will affect how big your fish can grow, the number of fish you can stock, the size and type of filter you need to buy as well as how much light, food & supplements you will need to maintain your aquarium’s healthy environment for both plants and animals.
1/ Desktop Fish Tank :
This is usually recommended for beginner aquarists who want their first experience with an aquarium to be painless and worry-free because they have limited knowledge about caring for aquatic creatures. Desktop aquarium also tend to be small and compact. They are usually between 5-20 gallons in size and can support a wide variety of fishes, plants or invertebrates species.
2/ Fish bowl :
These miniature fish tanks are usually less than 2 gallons ( generally 1.5-3 Gl ) so they do not take up too much space on the surface or spilling over onto furniture if knocked. However, keep in mind that bowls often have sharp edges around their base and not all fish will thrive in them because they need more space than this configuration allows. This is why we highly recommend using an undergravel filter instead of buying one with an air stone . Though some may disagree, we feel it’s best for tropical species like Goldfish , Bettas and even the popular Oscar fish varieties
3/ Fish tank kits :
If you want to get your feet wet and ease into aquarium keeping without taking a big plunge, we suggest buying one of these starter kits. They usually include everything you need to start up an aquarium including 3 pre-planted tanks, test kit, filter, heater and accessories. These sets are an excellent way to develop good aquarium habits early on such as testing water regularly for proper pH levels or using a quarantine tank when bringing home new fish from the pet store. Usually they have at least a 20 (or more) gallon capacity which means fewer investements in equipment (i.e.: filters etc.) because they come with everything necessary including lighting – making them ideal for marine aquariums.
4/ Marine Tanks :
These tanks are often used to support a budding marine hobbyist who has outgrown their freshwater tank and expanded into the fascinating world of saltwater fish keeping. Saltwater fish tend to be much larger in size and require more water volume than freshwater species – which is why we suggest starting with a 30-40 gallon sized tank for hosting a variety of fish, corals, anenomies and or snails .
5/ Nano Reef Tank :
We call these mini reef systems – which can range from 55-100 gallons in size depending on what you want them to hold (fish only, live rock & invertebrates etc.) nano because they require minimal equipment and are relatively inexpensive to maintain. A few of the qualities we love about nano tanks is that they tend to be compact, versatile and have an aesthetically pleasing design which makes them perfect for homes with limited space or lighting .
6/ Large scale reef systems :
These types of aquariums can get very expensive because they need to accommodate large amounts of water and specialized equipment including protein skimmers, calcium reactors, chiller, wave makers & heaters. These fish tanks also require a high level expertise in order to keep them running smoothly so many choose to enlist the help of a professional aquarist. They usually range from 100 – 1000+ gallons in size.
Tips on how to choose the right one for you and your budget
Aquariums can make an attractive and functional addition to any home since they are often used as a conversation starter. Below is a list of factors we think you should consider when choosing the right aquarium for your needs:
1/ What is my budget?
It’s important to shop around and look at different online retailers – not all retailers carry all the different sized aquariums and sometimes you can find a better deal elsewhere on sites like Amazon.com . Pricing can vary depending on what type of glass or acrylic construction, brand name (such as SeaClear , Marineland , etc.), how it is decorated, lighting/filtration requirements & warranty information.
2/ What is my space constraint?
If you don’t have a lot of room and can only accommodate a small sized aquarium, your best bets are Nano tanks/ponds (under 75 gallons) or fish bowls. If you have the square footage for a small tank (around 50-75 gallons) we suggest starting with an all-in-one freshwater fish tank kit such as the Aqueon Pro 25 (pictured to the left) or Marine Tanks . If you have a bit more playroom, then go for something larger like tank kits/aquariums with stand .
3/ How am I going to decorate?
When deciding on decorations you can either go with the standard gravel, rocks & driftwood or decide to create a reef aquarium from scratch. You will also have to consider how much time you are willing to invest into keeping your tank properly maintained in terms of lighting and filtration .
4/ What fish am I looking for?
If you want something basic like betta fish the best tank to house them in is an all-in-one kit such as Marineland Contour . If you want a more diverse community aquarium then we recommend a larger sized tank with additional filtration and lighting.
5/ What kind of equipment will I need?
In terms of filteration, your best bets for freshwater tanks are either a Hang On Back Filter (HOB) or canister filter . The best type of filtration for saltwater tanks is a protein skimmer since they remove organic waste and dissolved organics. Since saltwater creatures tend to be more sensitive than their fresh water counter parts, you will need to invest in some type of lighting to sustain a healthy reef aquarium .
6/ How much maintenance will I really need to do?
Since this is a living ecosystem where you are going to be adding fish and/or invertebrates, there will always be the need to monitor your water parameters , clean up, feed & observe your creatures. You can reduce cleaning time by feeding your fish less frequently, using live wells or getting a sump .
