2. Change the water regularly, it is recommended to replace it every 2 months 20% seawater, and regularly add trace elements, start using a protein skimmer 2 months after raising fish, seawater is hard water, and regularly check the concentration of nitrite and the stability of pH.

3. For polyculture fish, you need to find some fish with similar body size and better temperament, otherwise the big fish will eat up the small fish, so it is necessary to avoid conflicts between species.
