Biology     Glossary (e.g. epibenthic)

Inhabit freshwaters and tidal rivers. Its bright color and small size attract aquarists. Oviparous, eggs are unguarded (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00357 - 0.01114), b=2.99 (2.83 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
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).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 265 [134, 589] mg/100g; Iron = 1.24 [0.63, 2.41] mg/100g; Protein = 15.9 [13.8, 18.1] %; Omega3 = 0.208 [0.112, 0.381] g/100g; Selenium = 41.3 [21.6, 92.0] μg/100g; VitaminA = 35.6 [15.3, 82.4] μg/100g; Zinc = 1.76 [1.27, 2.41] mg/100g (wet weight); based on nutrient studies.
