Natural History: The Three Stripe Damsel is found on coastal and offshore reefs, lagoons, reef faces, and slopes. It is observed in close association with stony corals. Juveniles frequent branching stony corals whereas adults prefer lobed or coarsely branched stony corals. It is often found in groups from 3 to 25 fish, or in male-female pairs.
Husbandry: Juvenile Three Stripe Damsels are quite attractive and well-mannered but can become aggressive as they grow. Adults of this species should be housed with more aggressive tankmates. Numerous hiding places should be provided. They should not be housed with peaceful fish. They benefit stony corals by likely providing nitrogenous nutrients to the corals and increasing water circulation among the branches of the corals.
AKA: Humbug Dascyllus
