If the living space of map fish is sufficient, the breeder can lay a layer of bottom sand in the fish tank first, then plant some aquatic plants, and then place a piece of sunken wood. Map fish can eat and pull, so they can't be raised in fish tanks with complicated scenery. Moreover, sunken wood can adjust the water quality, keep the water quality in a weakly alkaline state, and aquatic plants can also carry out photosynthesis.

If there is not enough space to keep map fish, it is recommended not to put too many decorations. Just put a layer of bottom sand or a layer of Stone. If you want to be delicate, you can put some rockery or other decorations. Because map fish are too large, if too many decorations are placed, their normal life may be affected.

How big a tank is for map fish depends on the number of people who want to breed. Under normal circumstances, a map fish needs a fish tank 40-50 cm long. If breeders want to breed more than one map fish, they can choose the size of the fish tank according to their size. Under normal circumstances, an 80 cm long fish tank can raise 3-5 map fish, and a 120 cm long fish tank can raise 6-8 map fish.

Because of their large size, their body length can reach about 25-30 cm in adulthood. If the fish tank is too small, it may affect their growth and development. Moreover, they can eat and pull, and their demand for oxygen is relatively high, so the breeding density should not be too high.
