1. First of all, we should understand the living environment of arhat fish. This kind of fish belongs to tropical fish species, so it requires high temperature. There should be a heating device in the fish tank to keep the water temperature at 30 degrees. Especially when the weather turns cold, we should pay more attention to the change of water temperature. Ensure that the water in the fish tank is always in a constant range. At the same time, don't change water too often or too much, so as not to damage the overall environment.

2. At the same time, we should also understand the living habits of the arhat fish. Luohan fish is fierce and aggressive. Try not to mix with other fish to avoid attacking each other. At the same time, according to the size of the fish tank, determine the number of arhats. Avoid their influence on the living space.

3. The feeding habits of arhat fish are miscellaneous, but we should pay attention to balanced nutrition. You can feed small fish and shrimp if you can. This can not only meet the needs of Luohan for nutrition, but also increase the activity of Luohan and exercise physical function. Clean up leftover and unfinished foreign bodies in time to avoid damaging the water quality.

4. You can add some background patterns to the fish tank, the color should be gorgeous, and add some light at the same time, which is beneficial to the color and forehead generation of Lohan itself. However, it should be noted that these changes of Lohan occurred after the fish matured, so we must control the timing of its formation, which is too early and the effect is not good. Stay back as far as possible, so that the color and forehead of the fish can fully grow.
