It is also more passive than most angelfish, but may become aggressive to new inhabitants once established. The blackspot angelfish may be kept as a mated pair, or in harems composed of a male and multiple females. If a large enough tank is provided, more than one male may be kept.

Care: The Genicanthus melanospilus is a omnivore and likes to eat marine algae, mysid shrimp, Spirulina, sponges, and other meaty treats. They are also plankton eaters in the wild.

The Swallowtail Angel is a medium maintenance fish and may act semi-aggressively toward other fish.
