Size / Weight / umur
Maturity: Lm ? range ? - ? cm
Max length : 6.5 cm SL jantan/; (Ref. 48635)
Duri punggung (Keseluruhan (total)) : 3; duri punggung lunak (Keseluruhan (total)) : 22; Duri dubur: 3; Sirip dubur lunak: 10 - 12. This species is distinguished from its congeners by having a bright yellow snout/ forehead that grades into a light purple to bluish-grey coloration over the remainder of the head and body (Ref. 74963).
Found in sheltered habitats with rich coral growth to about 30 m depth (Ref. 48635). Observed in western New Guinea in habitats of silty dead coral reef, near the base of steep slopes 13-29 m depths; these reefs are characterised by numerous small caverns/overhangs and fish were usually seen adjacent to vertical surfaces. They appear to occupy territories or home ranges of about 2 sq. m and are often encountered solitarily, sometimes in loosely associated pairs (Ref. 74963).
