背面の脊椎 (合計) : 10; 背鰭 (合計) : 10; 肛門の骨: 3; 臀鰭: 10. The inner surface of the pectoral fin axil without scales. Overall color is silvery-gray with yellowish suffusion; scale margins are narrowly brownish. Indistinct dark blotches or bars are sometimes apparent on the body. The lips are whitish to yellow. The fins are yellow, faint brown spotting may be present on soft dorsal, anal, and caudal fins. A narrow blackish bar runs across the base of the pectoral fin.

Estimates based on models
Preferred temperature (Ref.
123201): 14.4 - 24.3, mean 19.9 °C (based on 186 cells).
Phylogenetic diversity index (Ref.

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00668 - 0.05187), b=2.96 (2.72 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 3.7 ±0.52 se; based on food items.
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
