It is ok to spread sand in bare tank for raising rat fish. The breeder can decide how to raise it according to his own habits and the fish he breeds. If breeders have other fish for convenience or polyculture, they can choose to use bare tanks. Because the bare tank is easier to clean, and other fish are mixed, it will not hide too much garbage and bacteria, which is very convenient.

If the breeder raises the rat fish alone, it is better to spread sand. Because rat fish have the nature of turning over sand, and they like to look for food in the sand, spreading sand in the fish tank can continue their nature. Moreover, rats and fish usually like to hide in aquatic plants and spread bottom sand, which can plant aquatic plants well. After spreading sand, breeders need to clean it frequently to avoid bacteria breeding.

For the simple set of the mouse fish tank, you can choose a driftwood as an arch bridge, then plant a few water plants on it, and finally lay a thin layer of sand on the bottom of the tank, which can meet the needs of the mouse fish. If conditions permit, you can install a few more fish tank lights, or put some Stone above the sand, which can increase the ornamental value.

Although the landscaping in the rat fish tank is beautiful, it should be cleaned regularly. Breeders had better clean it once every 1-2 weeks, and the bottom sand should be taken out regularly to avoid breeding bacteria.
