Biology     Glossary (e.g. epibenthic)

Feeds on aquatic macrophytes and filamentous algae (Ref. 26700). In the aquarium it will feed on flakes and frozen food, but will also hunt down a large shrimp. Females are aggressive towards other females and can have several males in following (Calum Chalmers, pers. comm. 2007).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02042 (0.01120 - 0.03721), b=2.97 (2.81 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
