Distribution and habitat preferences

Patches of rubble adjacent to areas of coral on reef slopes and channels.

Found mainly on exposed and semi-exposed reef slopes below 5m.

Behaviour

The Bicolor Angelfish is a benthic omnivore, taking algae, crustaceans, worms and other invertebrates from the reef and rubble areas that it inhabits. This species is a haremic protogynous hermaphrodite. Males maintain a harem of 1-4 females and several immature females throughout the year, and defend the harem territory from other neighbouring males. Mating occurs during the warmer months of November to March.
