The black velvet angelfish respects other species but chases members of its own
species off its territory. It is shy, a good swimmer, and reckoned to be hardy.
It devours large prey (nereis, also known as rag worms), but also eats tubifex worms
and brine shrimps, as well as grazing on algae. Its skin is very sensitive to parasites.
Size: 18 cm.
