Biology     Glossary (e.g. epibenthic)

Occurs in fast flowing streams interrupted by frequent cascades or rapids. Usually inhabits the deeper pools, often at the base of waterfalls with very clear water and a primarily solid rock bottom with little or no vegetative cover (Ref. 5259, 44894). Inhabits pools and rivulets on sandstone terraces (Ref. 44894). Seen in schools containing up to 50 or more individuals (Ref. 44894). Both sexes can become sexually mature at 2.3 cm SL (Ref. 2906) A popular aquarium species that thrives in captivity (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
