The black-axil chromis, also known as the blackfin chromis or blue-green puller, is a damselfish from the tropical Indo-Pacific. This fish can reach almost 12 centimetres (4.7 in) in length. It inhabits lagoons and reefs after settlement in the late-larval stage, and often occurs in large numbers, feeding above Acropora corals. This fish mostly feeds upon copepods, amphipods, and zoea.
