Distribution and habitat preferences

Areas of sand, rubble and seagrass adjacent to coral reef areas, most common in sheltered lagoonal habitats.

Can be found in most locations around the island.


The Blacktail Grubfish is a benthic carnivore, taking crustaceans, worms and other invertebrates from the rubble areas that it inhabits. This species is a haremic protogynous hermaphrodite. Males maintain a harem of 2-10 females and mating occurs daily throughout the year, just before dark. Females have territories which they defend from other females, whereas the male territory encompasses all of the females in the harem.
