Size

To around 6cm SL.

Colour

Body with 6-9 vertical brown bands, width about equal to eye diameter; bands more pronounced anteriorly and dorsally, often fading on caudal peduncle; snout and head above eye dark brown in adult males; black bar at pectoral base, entirely above pectoral rays. Second dorsal fin with 2-3 rows of small dark spots on basal half of fin, surrounding white to clear spots; distal tip of fin dusky, sometimes whole fin dusky; extreme tip of anal usually white; small dusky spot at base of caudal rays below midside.
