They live in small groups of one mature male that guards a nest site on the seafloor and several females.[1] Once settled, females rarely migrate. New juveniles can usually join groups easily.[2] 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.[2]
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.[3]
