Biology     Glossary (e.g. epibenthic)

Feeds on worms, small insects, crustaceans and plant matter (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 100 cm (Ref. 51150).

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

In tank, after vigorous driving by the male, the female lays up to 300 eggs, sometimes more, which sink to the bottom. Eggs hatch after about 6 days (Ref. 7020).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.33 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
