Hawaiian dwarfs belong to the order Perciformes, the family Surgeonidae, the genus Ctenodon. The fish is light brown with dark auspicious cloud-like markings. Inhabits coral reefs at a depth of about 10 meters. Gentle, feeds on algae and small invertebrates. The water temperature for raising Hawaiian hangers should be controlled between 20-28°C. When the temperature is too low, a heating rod can be used to increase the temperature.

The most suitable water quality for Hawaiian hangings to grow 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. You can feed fish and insects, and you can also feed vegetable leaves. Feed once a day in the morning or in the evening, but don't feed too much each time. It is relatively aggressive to its kind, so it is best not to mix with its kind. Make sure there is a Hawaiian hanger in a fish tank.
