It also has much resemblance in color and shape, with the species Chrysiptera unimaculata.
This looks like a Banded Sergeant (Abudefduf septemfasciatus) in "Reef Fish Identification Tropical Pacific," Allen et al, 2012, p. 61 -- but this species doesn't appear in iNaturalist. Any suggestions what to do?
The Pomacentridae are a family of perciform fish, comprising the damselfishes and clownfishes. They are primarily marine, while a few species inhabit freshwater and brackish environments (e.g., Neopomacentrus aquadulcis, N. taeniurus, Pomacentrus taeniometopon, Stegastes otophorus). They are noted for their hardy constitutions and territoriality. Many are brightly colored, so they are popular in aquaria.
