Description
Size: 8-9 cm.

Color: In alcohol specimens yellowish, with silvery reflections on sides of head and belly. A black band from snout through eye to hindmargin of operculum. A black spot at base of caudal on lateral line, a small black spot at origin of first dorsal and at origin and end of second dorsal. Frontborder of first dorsal, including the filamentous part, black. Second dorsal, anal and often also caudal with several transverse narrow dusky bands, the interspace with a row of more or less distinct milky white spots. In some specimens these bands and spots are absent. Pectorals and ventrals yellowish.

Dorsal and ventral profile evenly convex, dorsal profile from snout to dorsal almost straight. Height 2.5-2.7, 3.3-3.5 in length with caudal. Head 2.4-2.5, 3-3.3 in length with caudal. Eye 3-3.5. Snout equal to or somewhat more than interorbital space and about five sixths of eye. Mouth somewhat oblique, jaws equal. Maxillary reaching to below middle of eye, its height posteriorly about 2.5 in eye. Hind and lower border of praeoperculum serrated. Praeopercular ridge, praeorbital and orbital rim smooth. First dorsal spine much less than one half of second, which is somewhat stronger than the following ones and equal to distance between hindmargin of operculum to hindborder of pupil. The third and fourth spine are prolonged into a filament, the third being the longest and exceeding the second by as much as width of pupil. This filamentous prolongation however is not present in all the specimens examined. Spine of second dorsal about equal to fourth spine of first dorsal and equal to eye, somewhat longer than eye in small specimens. Anal spine somewhat shorter. Longest soft ray of dorsal longer than those of anal and as long as second dorsal spine and as ventrals. Pectorals as long as third dorsal spine. Caudal incised. Least height of caudal peduncle 1.2-1.3 in its length and about equal to postorbital part of head. Several rows of small teeth forming villiform bands in the jaws, those on vomer somewhat larger in an indistinct double row. Teeth on palatines in a single row.
Dorsal spines (total): 7-7, Dorsal soft rays (total): 9-9, Anal spines: 2, Anal soft rays: 8.

Dioecious, external fertilization, bearers, external brooders, mouthbrooders, the males incubate the eggs, distinct pairing during courtship and spawning.
