Dorsal spines (total): 9 - 9, Dorsal soft rays (total): 11 - 11, Anal spines: 3, Anal soft rays: 9, Vertebrae: 25. Emarginate caudal fin become lunate in males. 2-6 soft dorsal rays of males greatly prolonged (the odd-numbered rays beginning with the first), may be slightly prolonged in females (not so in Philippine adult females), non filamentous rays approximately equal in length. Tubed peduncular scales 5.9, side of body is with four or five narrow red to blue stripes, only the first and third extending full length of body.

At 15 cm SL, this could well be the largest species of the genus so far. Some geographical variations of nuptial males that are influenced by the presence of similar species.

Males readily display to each other or to females to spawn by flashing their colors and 'racing' past with erected fins. Hybridizes with several other species, and are most colorful where other similar species occur in the same area
