Estimates based on models

Preferred temperature (Ref. 115969): 27.5 - 29, mean 28 °C (based on 106 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01088 - 0.05049), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  2.1   ±0.1 se; based on size and trophs of closest relatives
