Biology     Glossary (e.g. epibenthic)

Inhabits lowland swamps, drainage ditches and streams that have abundant vegetation (Ref. 2847). Occurs in slow-flowing streams, swampy ponds and billabongs with abundant aquatic vegetation. Temperature and pH ranges are 23°-28°C and 5.2-6.6, respectively (Ref. 44894). Most commonly found along the heavily vegetated margins of lily lagoons and small streams. Feeds mostly on diatoms and micro-crustaceans. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539). Well established in the aquarium hobby, but its longetivity is relatively brief, averaging only 2-3 years (Ref. 44894).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01120 (0.00513 - 0.02445), b=3.04 (2.87 - 3.21), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.34 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 (22 of 100) .
