Adults sometimes associate with Pavona decussata corals, while juveniles associate
with branching corals, such as Acropora spp.
Protogynous (able to change sex from female to male) species. Some populations

develop as males (primary male), or born as females and change sex to become
males (secondary male) later in life.
