Biology     Glossary (e.g. epibenthic)

Adults inhabit hill streams up to an elevation of 300 m (Ref. 4832). Found in shaded, mid-hill clear waters with pebble or gravel substrates (Ref. 11966). They occur in schools at the surface in small high-gradient upland streams (Ref. 12693). They feed mainly on exogenous insects (Ref. 12693) and also on worms and crustaceans (Ref. 7020). Not seen in markets, but popular in aquarium trade (Ref. 12693, 44325). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 100 cm (Ref. 51539).

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

The fish spawn several times with small intervalls releasing 5-20 eggs each time (Ref. 1672). A prolific species laying over 1000 eggs (Ref. 7020).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00192 - 0.01087), b=3.08 (2.88 - 3.28), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.33 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=300-1,000).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
