The spiny chromis (Acanthochromis polyacanthus) is a species of damselfish from the western Pacific.[2] It is the only member of the genus Acanthochromis.

This fish usually lives in coral reefs at a depth range of 1 to 65 metres (3.3 to 213.3 ft)[2] This fish eats only plankton although younger individuals have been known to eat mucus off the adults.[3] Spiny chromis individuals can grow up to a maximum size of 14 centimetres (5.5 in) as adults.[2]

Life cycle[change | change source]

The spiny chromis, unlike many other coral reef fishes, has direct development of their larvae. The parents protect their brood from the egg stage (laid on the reef), through hatching and onto the fully developed juvenile stage.
