Tank compatibility[edit]

A highly aggressive fish, aggression will increase as it matures. Do not keep with timid fish. Can be kept in male/female pairs. Can be kept in a semi-aggressive large community, with larger Dottybacks, Angelfish and Puffers. This fish will also host anemones and will generally not harm invertebrates.


A territorial and boisterous fish, especially if kept singly, this only increases with age.


Oval, almost round body shape, a deep grey-blue colour. As juveniles they are black with a whitespot on the forehead and one on each side, as the fish matures the body colour lightens and the spots fade.
