Habitat and Ecology
This species is associated with coral reefs of lagoons, rubble areas and exposed outer slopes. It is most abundant on outer reef drop-offs (Pyle 1991, G.R. Allen pers. comm. 2006). It can be found as single animals or in aggregations, often as harems of three to seven individuals (Myers 1991, Pyle 1991). This species feeds on algae (Myers 1991, Pyle 1991).

Twospined angelfish

Learn more about this article

The Twospined Angelfish, Dusky Angelfish, or Coral Beauty (Centropyge bispinosa), is a marine angelfish.

Some individuals have a dark purplish blue body with yellow to red stripes, and usually an electric blue rim; in others are orange stripes dominate, with the purple distributed in spots. Some bright orange forms are very similar in appearance to the golden angelfish, Centropyge aurantia.

The twospined angelfish is native to the Indo-Pacific where it lives in coral reefs and lagoons. It reaches a maximum length of 3 inches (8 cm). It eats algae.

When kept in an aquarium they may have a tendency to nip on corals, especially soft corals and clam mantles. This species is suitable for beginners, as it is considered one of the hardier dwarf angels. Due to their high metabolisms, feeding usually needs to be done at least every other day. Once established, they are generally a long-lived species. There is also a deep water version of this species.
