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.
Place of origin:Western Pacific
Widespread, but known from scattered localities in the Pacific: Samoa, PNG & Solomons, northern GBR, Indonesia, Palau and Pohnpei. A secretive species, rarely seen by divers. Normally found in deep gutters amongst corals or crevices, and has been reported to 60m depth, and in PNG as shallow as 3m. Colour somewhat variable, usually dusky orange overall with numerous vertical narrow stripes on side. Some individuals are totally dark brown and may turn to orange, the more normal colouration, when kept in captivity for a while. Length to 10cm, but usually much smaller: 5-6cm.
