Description
editThe bicolor damselfish can grow to about 10 cm (3.9 in). The head and the front half of the body are dark grey or black and the rear half is pale, usually with some yellow, with regional variations in the coloring. The large dorsal fin has 12 spines and 14-17 soft rays. The anal fin is also large and has two spines and 13-15 soft rays.[3]
Behaviour
editUnlike most other members of the genus Stegastes which eat filamentous algae, the bicolor damselfish feeds on plankton. It forms loose groups of up to twenty individuals and defends a territory over a rocky reef with plenty of crevices in which to lurk.[4]
