Estimates based on models

Preferred temperature (Ref. 123201): 23.7 - 29, mean 27.3 °C (based on 1120 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00410 - 0.01937), b=2.78 (2.60 - 2.96), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.48 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
