soft rays: 51 - 56. Body brownish, a distinct, large dark blotch at junction of straight and curved parts of lateral line and a smaller blotch on middle of straight section of lateral line, many dark rings scattered on body. Upper profile of head without notch in front of eye. Scales on eyed side ctenoid on anterior part and dorsal and ventral margins of body on eyed side, cycloid on remaining areas.

Estimates based on models
Preferred temperature (Ref. 115969
): 23.8 - 28.8, mean 28 °C (based on 226 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00341 - 0.01611), b=3.16 (2.99 - 3.33), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (20 of 100) .
