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.

Estimates based on models

Preferred temperature (Ref. 115969): 25.6 - 28.2, mean 27.4 (based on 530 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00680 - 0.04650), b=3.03 (2.80 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.65 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
