Etymology: Paracentropyge: Greek, para = the side of + greek, kentron = sting + Greek, pyge = tail (Ref. 45335). More on authors: Smith & Radcliffe.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 7 - 70 m (Ref. 9710), usually 20 - 70 m (Ref. 9710). Tropical; 35°N - 25°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 48636)
Inhabits ledges and caves and crevices of steep outer reef slopes; occasionally found in clear lagoon reefs (Ref. 9071). It is secretive and rarely goes out more than a few centimeters from an escape hole (Ref. 9710). Forms pairs or small groups. Usually starves when kept in captivity (Ref. 48391). Often upside-down (Ref. 48636). Occasionally exported through the aquarium trade.
