Breeding
Pairs lay sticky eggs on a cleaned hard surface, and the male guards them until they hatch. Spawning happens in aquariums, but rearing the tiny pelagic larvae is difficult.
Good to know
Less aggressive than many damsels but can become territorial as it ages, so add it after more timid fish. The trade label "Yes[49]: 215" is a data error, not a real name.
