Widespread tropical Western Pacific, ranging from Japan to Australia, and Sumatra to Samoa. Expatriates to subtropical zones, transported by current during their pelagic stage. Common in most areas but becomes rarer in the western and eastern extremes. Usually found on rocky and coral reefs at depths between 10-25m, but in some areas that are sheltered and have good water quality, it can be observed in just a few metres depth. Where common, the adults are nearly always in small groups that actively move about in gutters or amongst corals to feed on algae. Juveniles are solitary and secretive in crevices. A very distinctive species that is immediately recognised  by its half yellow, half blue colouring and its blue band above the eyes. Length to 15cm.
They are commonly referred to as pygmy angelfishes, due to their generally much smaller size than other angelfish genera. The species are variably distributed in tropical and subtropical seas of the world. Few have large geographical distributions and some are endemic to tiny oceanic outposts, an island , or small island group. They occur on algal-rocky and coral reefs, and most species live in shallow waters at depths to about 15m,  but some range to 70m or more, and a few inhabit only depths of more than 50m. Pygmy angelfishes are quick-darting and often shy species that hug the substrates with tunnels and crevices, ready to disappear and appear again several metres away.
