Advantages of a larger fish tank

Some people are interested in buying larger fish tanks for their fish but it costs a lot. Due to high prices, people think it is not advisable to buy a large tank for your goldfish when a smaller tank can do the job. Here are the reasons why you should buy a large tank instead of a small tank:

Maintain quality of water

Water in a fish tank has ammonia, nitrite, nitrate, calcium, magnesium, alkalinity, and a balanced pH. These elements maintain a good environment of water for marine creatures. If the balance is disturbed due to any reason like dead fish then the rest of the fishes also suffer due to change of balance. For example, if your fish were to die then the ammonia level of the water will increase if you don’t replace the dead fish in time.

In the case of larger fish tanks, a dead fish will not bring any change to the chemistry of water because the amount of ammonia produced by a single fish is negligible as compared to the whole tank of water.

The chemistry of old water and new water is not the same if you replace new water with old water then the elements that maintain the chemistry of water will spike up in a small aquarium. When we talk about the larger fish tanks, then the water replaced is nearly equal to 10 to 20% of the whole water therefore the overall water chemistry would remain the same.

In the case of saltwater fish tanks, the evaporation of fresh water takes place and it maintains the salinity of the water.

Temperature is difficult to maintain in smaller tanks when your heater is malfunctioning and it takes a long time for water to cool off or heat up.


Large aquariums provide more space for the bacteria to grow better and support plants, fish, and corals that maintain the ecosystem of the fish tank. Large fish tanks also provide space for the fish to swim such as 100-gallon space is enough for a Piranhas.

A large aquarium in offices, bedrooms, and schools provides more space for different species of fishes to mark their territory and you can grow there plants and dense vegetation gives them a natural environment to flourish just like that of the natural ecosystem of the ocean.

You also not worry about the fishes (cichlid) fighting for survival and the larger fishes eating the smaller ones. You may also have turtles or any reptiles in your aquarium. They require a larger fish tank.

Most hobbyists think that it is easy to maintain a physical filtration system like that of a sump and a canister under the fish tank. It is difficult to maintain such a filtration system because smaller tanks have smaller bases.

You can try one of the 200-gallon fish tanks described above to see the results.

Guidelines to buy a fish tank

Here are the guidelines to buy a fish tank:

  • First thing you need to keep in mind that how many fishes you want to compensate in the aquarium
  • The thumb rule is one inch of adult fish excluding the tail in 24 square inches of the surface. These guidelines are for tropical aquarium fishes and not for cold-water fishes like goldfish.
  • Coldwater fish like goldfish requires 30 square inches of the surface area per fish. This is because they have greater body mass and their oxygen requirements are also great.
  • Always choose an aquarium that has a greater surface area as compared to volume.
  • The shape of the aquarium ( square, rectangle, and circular cube) has also impacted the fishes.
