Bicolour Dottyback

Its’ habitat spreads from shallow coastal reefs to deep reef drop-offs further out. They are usually found in abundant areas of coral or around coral rubble, either on their own or in small scattered groups.

Bicolour Dottybacks grow to the greatest length of around 8 centimetres (3 inches) in the wild, but in captivity, 6 cm (2.5 inches) is more usual.
