Maturity: Lm ?  range ? - ? cm
Max length : 12.7 cm TL male/unsexed; (Ref. 13442)
Adults pale yellow; usually darker dorsally; grayish yellow that pales ventrally. Iridescent blue dorsal-ventral lines on head, sometimes extending to the leading edge of pelvic fins. One distinct blue line encircles the orbit and extends ventrally on each side of the fish. Two black pigment spots are sometimes found on the snout region of the nares. A large black saddle on caudal peduncle, extending below the lateral line on each side of the fish. Pelvic fins yellowish, pectorals clear.
Mainly carnivorous (Ref. 13810). Has been reared in captivity (Ref. 35420).
