簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 15-19; 臀鰭軟條: 17 - 22; 脊椎骨: 24 - 25. Differs from all other species of the genus by possessing 2-4 black spots on posterobasal portion of dorsal fin in males. In addition, it can be separated from all congeners by the unique combination of the following characters: absence of pelvic fin and pelvic girdle; vertebrae 24-25; absence of second pharyngobranchial teeth; absence of ventral process of posttemporal; anal fin with 17-20 rays in females; body depth 33.5-36.0% SL in males; maximum adult size 25.6 mm SL; bright blue bars on flank in males much narrower than interspace; side of head in males with five alternating bright blue and pink to red bars; short postorbital pink strike connecting pink bars 2 and 3; anterior and posterior margins of iris bright blue; dark gray band bordered by a bright blue line on distal margin of dorsal and anal fins, and posterior margin of caudal fin in males; ground color of dorsal and anal fins orange in males; absence of bars on unpaired fins in males; and presence of yellow dots on the caudal fin in males (Ref. 75131).
Inhabits temporary shallow canals (about 50 cm deep) in the floodplains, with light yellow water (Ref. 75131).
