The Black damsel (Stegastes nigricans) is a saltwater fish of the family Pomacentridae that grows up to 14 cm.
Description
The dusky farmerfish is a damselfish of the family Pomacentridae from the Indo-Pacific. The species grows to about 14 cm and has a stocky, dark-brown body. Adults inhabit reef flats and lagoon reefs, often in coral-rich areas. It is a decidedly territorial 'farmer': it fiercely defends a patch of filamentous algae that it grazes and actively tends by removing unwanted algal species and intruders, a form of farming among fishes. As a predominantly herbivorous fish it feeds on those filamentous algae, supplemented with small invertebrates. The species is harmless to humans.
