Description

The scalyfin is a large damselfish (Pomacentridae) from the temperate coastal waters of southern Australia. Adults are dark brown to blackish, while juveniles are bright orange-brown with blue spots. Adults inhabit shallow rocky reefs, where they fiercely defend a territorial 'algal garden' against intruders. As an omnivore it grazes mainly on algae and picks small invertebrates. During breeding it forms distinct pairs and the male guards the eggs laid on the bottom. The species is harmless to humans.
