Description
Size: 8.2-10 cm.

Color: Pale white to brownish with three broad dark brown cross bands; the first band from chin obliquely upwards to the origin of first two dorsal spines, the second from the base of 5th or 6th to 9th dorsal spines obliquely to the base of pectoral and ventral and the third from soft dorsal to anal. Dorsal and anal brown, the distal part of the posterior rays light. Caudal dusky. Ventral dark. Pectoral light with dark base.

Head 3.0-3.5 in standard length, 3.8-4.3 in total length. Depth of body 1.6-1.8 in standard length, 2.1-2.3 in total length. Eye diameter 2.7-3.0 in head, 0.6-0.7 in snout and 1.0-1.1 in convex interorbital space. Teeth in jaws conical, outer row enlarged. Pectoral fin slightly shorter than head. Hind border and lower border of preopercle denticulated. Ventral fin equal to or longer than head. Swim by the oscillation of median or pectoral fins.
Number of spines and rays in the dorsal fin: XII, 12-13; number of spines and rays in the anal fin: II, 12-13; number of rays in the pectoral fin: ii, 15-16; number of spines and rays in the ventral fin: I, 5; number of scale rows along the lateral line: 17-18+8-9; number of horizontal scale rows usually counted from origin of the dorsal fin to the lateral line and from anal origin to the lateral line: 3+1+9.

Protogynous, external fertilization. Harem-type social structure observed with 1 male and several females with linear size dependent rank order, male spawned with the females in order of rank and may attempt to male with females from nearby territories. Male and largest female protect the home territory. Males invite females to spawn in their nests, protecting the eggs until they hatch and becoming very aggressive against other fish. (Male selects and protects the nest, does the courtship `dance' about 1 m above the nest and escorts the attracted female to the nest site where spawning ensues). Eggs hatch after 3-5 days, pelagic larvae feeds on plankton.

This fish has been reared in captivity

Max. age reported: 6 years
