Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.5 cm TL male/unsexed; (Ref. 90102)
Inhabits patches of talus or rubble of steep outer reef slopes. Usually seen in pairs that quickly dive headfirst into their burrow when disturbed. Juveniles occasionally school with similarly colored juveniles of Pseudanthias pascalus. Stomach contents of 6 adult specimens consisted of copepods (31.4% by volume), pelagic tunicates (31%, larvaceans, plus Oikopleura), fish eggs (28.6%), siphonophores (5.5%), larval shrimps (1.2%), fish (0.8%), amphipods (0.7%), unidentified decapod larvae (0.5%), and heteropods (0.3) (Ref. 8991). Minimum depth reported from Ref. 27115.

Displays obligate monogamy where a one-to-one pair is established irrespective of resource abundance (Ref. 52884).
