When raising rat fish, first of all, we need to prepare certain equipment and tools. The ratfish is a fish that likes to live at the bottom of the tank. When breeding, you can lay a layer of bottom sand at the bottom of the fish tank, which can provide them with a safe and stable space, they will have a better sense of security, and their development will be better. When choosing the bed sand, we need to pay attention to some problems and choose the appropriate bed sand.
First of all, you need to choose some sand materials with less particles, and it is better to lay 1 cm to 2 cm on the bottom of the fish tank. Moreover, some sand materials need to be avoided. For example, don't choose sand that is too sharp, or you may inadvertently hurt the rat fish, especially when they are feeding at the bottom of the tank. If you accidentally hurt the rat fish, their wounds may be infected, and those that affect the PH of the water are not worth choosing sand, otherwise it may affect the normal growth and development of the rat fish.
When choosing sand materials for rat fish, try to choose those sand materials with relatively small particles, such as American silica sand. It needs to be not only thin, but also round, not too sharp. It is better not to choose sand washed directly from the river, so that the particles of sand are generally larger. When laying on the bottom of the fish tank, you need to pay attention to the thickness of the shop, about 1-2 cm between it.
