They live in small groups of one mature male that guards a nest site on the seafloor and several females.[2] Once settled, females rarely migrate. New juveniles can usually join groups easily.[3] As they reach sexual maturity, they usually lose their "eyespot" on their dorsal fin. P. amboinensis is a protogynous species—all individuals start out as females and later can turn into males. However some males retain the appearance of juveniles, probably to sneak into the harems of dominant males.[3]
This species has been shown to have colour vision using behavioral experiments that control for brightness, apparently being the first known example of colour discrimination in reef fish.[4]
