Hawaii hanging water temperature should be controlled between 20-28 ℃. When the temperature is too low, a heating rod can be used to increase the temperature. The most suitable water for its growth is alkaline water with high salinity. The pH value is between 8.1-8.4, and the specific gravity is between 1.020-1.025. Because they are marine fish and cannot adapt to freshwater environments, they cannot be raised directly in freshwater.

The difficulty of raising Hawaiian hanging is medium. First of all, it has certain requirements for temperature. In order to grow better, the water temperature should be kept above 20 °C. It also has high requirements for water quality. As a marine fish, it likes water with high salinity. The water needs to be kept clean and should be replaced frequently. In terms of diet, it is an omnivorous fish with no high requirements, and most of the feed can be eaten. It is very aggressive towards the same kind, so it needs attention in the process of mixing.
