Biology     Glossary (e.g. epibenthic)

Prefers main river channels, but also occurs in lakes and on the floodplain. Feeds mainly on large crustaceans (Macrobrachium and Caridina), fishes, aquatic and terrestrial insects, nymphs and detritus. Occurs at temperatures ranging from 26 to 32°C. Mainly diurnal.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Mouthbrooders. Ovary or brood mass contains 15 to 75 ripe eggs (Ref. 2847).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00269 - 0.01023), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.47 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100).
Price category (Ref. 80766):   Medium.
