How to choose a fish tank

For those who don't know about Aquarium, they must feel that Aquarium has nothing to pay attention to except water and fish. In fact, the size of the aquarium is very particular.

First of all, the ultra-small aquarium

The size of the aquarium can be as small as a small fish tank with only one fish-a simple glass bowl-shaped fish tank with a capacity less than 1 liter. Except gill-sucking fish (also known as fighting fish, belonging to the suborder Perciformes) that can breathe air directly, such as Siamese fish or spotted fighting fish, it is generally not suitable for most fish.

Second, super-large aquariums

Oversized fish tanks are large enough to feed sharks or accommodate the entire seaweed forest ecosystem.

Third, the basic volume requirements

It is generally believed that the minimum volume requirement of basic devices such as filtration is 1 1 liter.

Four, the weight of the water pressure limit

For example, the weight of water (pure water per 1 liter 1 kg, salt water is heavier) and internal water pressure (high water pressure requires stronger and thicker glass) will cause volume restrictions, so the maximum volume of domestic aquarium can only be about 1 m3.

Note: Some people specialize in making several cubic meters of aquariums, but it takes a lot of effort and costs a lot.

Five, the world's largest fish tank

Public aquariums that raise large species or simulate large annual rings can be much larger than aquariums at home. Georgia Aquarium has the largest aquarium in the world, with a capacity of 30,000 cubic meters.

Six, high stability aquarium

Generally speaking, larger aquarium systems can cope with faster temperature and pH fluctuations to provide higher stability.
