Asia: originally known from a fast flowing stream in Atweltota, in the middle catchment of the Kalu River, Sri Lanka. Has since been collected from Sitawaka (Kelani basin) and Kuru River at Eratne (Kalu basin) and the Opatha River at Opatha (Nilwala basin).

Grootte / Gewicht / Leeftijd

Maturity: L_m ? range ? - ? cm
Max length : 4.5 cm TL mannelijk / geslacht onbekend; (Ref. 6028)

Adults are found in rocky mid-hill streams with fast flowing water. They adhere to the sides of submerged rock through sucking discs. Occur usually in water 50-150 cm deep. Carnivore. Sudden, heavy rainfall with an accompanying drop in water temperature induces spawning, usually in a cavity excavated in sand in the shelter of a stone. Eggs hatch in the event of another heavy rainfall. Larvae are swept downriver to the sea, mature adults migrate upstream to spawning grounds. Possibly amphidromous (Ref. 26364).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
