Ratfish is a deep-sea fish of the Chimaeridae family. Its origin is in Japan, and it is more distributed in Japan, Madagascar Island and the East China Sea. It is a relatively large fish, the longest body can reach 74 centimeters. They are relatively flat and long. From the head to the back, the body gradually becomes slender and has a strange appearance. Their eyes are very big and they look very striking.
The rat fish has the function of cleaning the tank to a certain extent. It belongs to a kind of fish that lives on the bottom, that is, it often inhabits the bottom of the fish tank. In this way, they will eat some of the food residue at the bottom of the tank, as well as some algae and so on. These things can pollute the water in the fish tank, so the rat fish will clean them up and improve the water quality.
However, there are two things you need to be aware of in order for them to do this. First of all, you don't need to feed the rat fish too much at ordinary times, otherwise they will be too full and will not clean up the residue in the tank. About two or three times a week, usually let them go to the bottom of the tank to feed themselves. Moreover, although the rat fish has the function of cleaning the tank, it can not change the water because they have this function at ordinary times. If the water in the fish tank is very dirty, it will have a greater impact on the growth and development of rat fish. Therefore, it is also necessary to change water regularly, or use filters and other tools to improve water quality.
