Lip margins smooth; body depth at anal-fin origin 5.3-5.7 SL; supraorbital tentacle if present, small and slender, with or without a bifid tip; small and unbranched nuchal cirrus; dorsal fin notch about half height of first soft ray; body coloration whitish with 2 longitudinal rows of thin paired dark bars along sides of body anteriorly bearing small white spots; body dorsally bearing small black and whitish spots and a series of 8 pronounced pink spots extending into dorsal fin; greenish gray head with many small whitish spots; unique to males is a large dark spot on each side of throat; iris greenish with spoke-like orange lines and narrow yellow inner rim. Middle 8 of 13 segmented caudal rays branched (Ref. 54980).
Facultative air-breathing (Ref. 126274); Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
