raise Luohan fish with or without bottom sand depends on the environment and the feeding equipment. If the feeding environment is comfortable and the water quality is stable, it is not necessary to put bottom sand, because adding bottom sand is to stabilize the environment. If the surrounding environment is unstable, or Luohan fish is in the fry stage, it is necessary to put bottom sand. But putting the bottom sand requires a strong filtration system, otherwise the bottom sand is easy to hide food residues and feces, easy to breed bacteria, and may destroy the ecological balance in the fish tank.
? It is better to raise Siraitia grosvenorii with volcanic rocks or coral bones. First of all, coral bones are alkaline. Adding coral bones can adjust the water quality to weak alkaline, which is more suitable for the survival of Siraitia grosvenorii. Moreover, the coral pore can effectively culture nitrifying bacteria, so that the ecological environment in the fish tank is stable. Secondly, although volcanic rocks are neutral, they can stabilize water quality. Volcanic rocks have high mineral content, which can absorb harmful heavy metals in water, and they also have a good effect on the hair color of Luohan fish. To sum up, the effect and function of coral bone and volcanic stone are similar, so breeders can choose according to their own situation.
