Orangeback angelfish

May become aggressive

Orangeback angelfish inhabit coral reefs, from 6 to 70 metres deep. The fish features a distinct field of blue and yellow-orange colouration, and a compressed body. Orangeback angelfish are very curious, active and alert fish. They may become highly aggressive towards other fish and make fierce attacks. They frequent areas of rocky coral reefs, with plenty of algae to feed on. 

Females can turn into males, and then females again!

Orangeback angelfish usually live in harems with one male, a few adult females and a few young females. All orangeback angelfish are born female, and form pairs where the dominant of the pair develops into a male. The male may then evolve back into a female if the fish loses its dominant position. Going from male back to female takes much longer for an orangeback angelfish than going from female to male. After mating, the female lays a large number of eggs which are dispersed in open water and the offspring are left to fend for themselves.
