Damselfish are plentiful in [[coral reef]] environments. The [[International Union for Conservation of Nature]] lists this fish as being of “least concern”. The species is exploited on a minor scale, for fisheries and the aquarium trade. It may be threatened by the [[Invasive species|invasive]] [[lionfish]]. Adult and young adult damselfish differ significantly in terms of body color. The difference was so noticeable that researchers believed the adult and young adult forms were two distinct species.<ref>{{Cite book|title=Enumeratio piscium Cubensium / por Don Felipe Poesy.|last=Poey|first=Felipe|date=1875|publisher=Imprenta de T.

Young adults are violet with blue spots in their back and transparent caudal fins. == Reproduction == The spawning (laying eggs) cycle of the yellowtail damselfish starts at sunrise and lasts approximately 1 hour after male damselfish have prepared nests on dead coral surfaces. Their eggs are demersal, sticking to the coral where males guard and fan oxygen ov
