The Bright-Eye Damselfish (Plectroglyphidodon imparipennis) is endemic to the Indo-Pacific Ocean. It can be found among mid-level reefs and lagoons, seeking shelter among rockwork and scavenging for algae or benthic invertebrates. Their bodies can be a pure white, grey, or even blue, all of which have a vibrant yellow caudal fin. Adults can be found as pairs, usually guarding their territory or young. They can be territorial, so it is advised to acclimate other fish at the same time. They reach a maximum length of 3 inches and should be kept in a tank of at least 30 gallons. Their diet should consist of meaty foods, such as mysis or krill, as well as occasional seaweed.
