Distribution and habitat preferences

Shallow reef flat areas near good coral cover in lagoons and other sheltered backreef habitats.

Can be found in most locations around the island.

Behaviour

The Coral Rabbitfish is a roving herbivore, moving around the reef in pairs and feeding on turf algae, seagrass and macroalgae. They spawn in groups during the warmer months, when fast running tidal currents coincide with dawn and dusk. They are mature at about 2 years of age, and the spawning takes place at a regular lunar phase. There is little published information on the demography or ecology of the Siganidae, but they are likely to be long-lived fishes. Juveniles look similar to the adults, but are always uncommon.
