Although the hawaii fish are fed animal-based bait like other fish, care should be taken to provide enough plant-based bait such as seagrass and seaweed. This strengthens their body's immunity, reduces aggressive behavior and improves their overall health. Dried seagrass can also be tied to the stone for feeding, and it is recommended to feed 3 times a day. Or prepare some artificial plant bait, which can be more convenient.

Hawaiian hanging inhabits rocky reef areas on the sea surface and coral reef areas with a water depth of 5-35 meters In waters, juveniles are usually found in deeper coral-clustered areas, living alone or in small groups. The natural diet is unknown, and it is inferred that it mainly feeds on various algae.

Hawaiian hangers need enough swimming space and are best kept in aquariums over 280 liters. Aggressive towards the same species, friendly towards other species of fish. It is also best to put only one hanger per tank.
