Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 59043); max. reported age: 3 years (Ref. 59043)

Short description Morphology | Morphometrics

Lamina circularis absent. Body depth is 9-11% of SL. Dorsal origin behind or above pelvic origin.

Biology     Glossary (e.g. epibenthic)

A short-lived species which inhabits upper and middle reaches of rivers, with shallow waters and stony bottom (Ref. 11240). Feeds mainly on aquatic invertebrates (Ref. 59043). Oviparous, with distinct pairing during breeding (Ref. 205). Matures at 1 yr of age (Ref. 59043). Is threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100, 59043).

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

During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).

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=0.00407 (0.00229 - 0.00726), b=3.10 (2.95 - 3.25), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1; Assumed Fec < 10,000).
Prior r = 1.06, 2 SD range = 0.62 - 1.82, log(r) = 0.06, SD log(r) = 0.27, Based on: 1 K, 1 tgen, 1 tmax, records
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
