It occurs in tropical shallow reefs on upper slopes and in subtidal habitats, at depths of 8 to 20 metres (26 to 66 ft).

Figures of its population are unknown, but is likely to be threatened by the global reduction of coral reefs, the increase of temperature causing coral bleaching, climate change, human activity, the crown-of-thorns starfish (Acanthaster planci) and disease.

It is found at depths of between 8 and 20 metres (26 and 66 ft) in tropical shallow reefs on upper slopes and in subtidal areas.

Packets of eggs and sperm are released into the water column and, being buoyant, rise to the surface.

Here the packets break up and cross-fertilisation takes place with gametes from different colonies intermixing.
