Banded Damselfish

The Banded Damselfish is a bold and eye-catching species from the Red Sea, recognized by its crisp pattern of alternating black and white vertical bands that give it a graphic, almost painted appearance. This member of the Dascyllus genus reaches about 3 inches in length and is closely related to the more widely distributed Four-Stripe Damsel, though it is distinguished by subtle differences in band width and geographic range.

In the wild, Dascyllus abudafur is found exclusively in the Red Sea and Gulf of Aden, where it inhabits branching coral heads on shallow reef flats and lagoons. Juveniles form tight aggregations among the branches of Acropora and Stylophora corals, retreating into the coral matrix when threatened. This close association with branching corals is a hallmark of Dascyllus species and continues in captivity, where the fish will readily adopt branching coral structures or suitable artificial equivalents as home bases. As adults mature, they become increasingly territorial and will defend their chosen coral head aggressively.

In the aquarium, the Banded Damselfish is extremely hardy and easy to maintain, making it an excellent beginner fish from a care perspective. However, its territorial aggression is significant and must be planned for carefully. Adults will harass and chase smaller or more timid tankmates relentlessly, especially in confined spaces. For best results, house with larger, assertive species in aquariums of at least 30 gallons. Provide multiple branching coral structures or rockwork with overhangs to allow the fish to establish territory. The species is completely reef-safe, posing no threat to corals or invertebrates despite its aggressive nature toward other fish.
