''Pomacentrus amboinensis'' is a Damselfish from the Western Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 9cm in length. They live in small groups of one mature male that guards a nest site on the seafloor and several females. Once settled, females rarely migrate. New juveniles can usually join groups easily. 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.〔 This species has been shown to have colour vision using behavioural experiments that control for brightness, apparently being the first known example of colour discrimination in reef fish.〔Siebeck, U. E., Wallis, G. M., & Litherland, L. (2008). Colour vision in coral reef fish. Journal of Experimental Biology, 211(3), 354-360. doi: 10.1242/jeb.012880〕 ==References==
