Head golden with blue spots and lines convoluted into various shapes, the most constant being a diagonal line across cheek from below orbit to corner of mouth. A bright yellow spot, about size of orbit, at base of last few rays of dorsal fin. Caudal fin bluish with rows of golden spots which appear as 3 or 4 crossbars on the folded fin; dorsal fin spines golden on a dusky membrane; dorsal in rays silvery on a bluish membrane, with a row of golden spots at bases of rays; anal fin spines golden on a dusky blue membrane; anal fin rays bluish, membrane dusky with a golden spot at base and a bar above in each membrane cell; pelvic fins dusky blue, outer spine and ray silvery, other rays dusky; pectoral fins hyaline.

Body deep and compressed, its depth contained 1.9 to 2.2 times in standard length. Dorsal profile of head descending fairly steeply, slightly concave before eye; anterior nostril with a low flange slightly expanded posteriorly. A forward-directed spine present in front of dorsal fin, imbedded in nape; longest dorsal spine the 4th to 7th and only a little longer than (1.1 times) last dorsal spine; longest anal spine the last, about 1.7 times the length of the first; caudal fin emarginate. Scales minute; cheeks covered with prominent scales; 19 to 25 scale rows between lateral line and bases of leading dorsal fin spines.

Dioecious, external fertilization, nonguarders, open water/substratum egg scatterers. Spawning apparently occurs not until the fish is 2 years old.
