Biology     Glossary (e.g. epibenthic)

Adults inhabit clear, fast-flowing streams, frequently in rapids or pools below them (Ref. 5259, 44894). Benthic feeder: various shrimps, earthworm, algae. Maturity: F, 17 cm SL; M, 23 cm SL. Spawning: mid October to early November after rainy periods; temp. Of 24°C. Fecundity: 115,000 eggs per female. Eggs: pelagic, 4.2-4.3 mm diameter. Hatching: 36 hours (Ref. 2906, 44894). Eggs are guarded and fanned by the male parent (Ref. 205). Aquarium conditions: pH=7, H=8, 25°C, rock and plant cover (Ref. 6398).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00590 - 0.02812), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.36 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 vulnerability (36 of 100).
