Description

The bicolor damselfish (Stegastes partitus) is a small reef fish of the family Pomacentridae from the western Atlantic and Caribbean. The species is recognised by the sharp division of the body: the front half is dark to black and the rear half white or yellowish. It reaches about 10 cm and inhabits shallow coral reefs and isolated patch reefs in deeper water. It feeds mainly on algae, but also on polychaete worms, hydroids, copepods and ascidians. The species is fiercely territorial, but defends only a small area around its shelter; because of this behaviour it is regarded as solitary.
