Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical; 8°N - 7°N
Asia: found only in a few rocky streams and the Mahaweli River basin in Sri Lanka.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 6028)
Occurs in a few localized, rocky, fast-flowing mountain streams. Has not been recorded from unshaded, silty or turbid waters (Ref. 11966). Moves fast through the water, staying close to the bottom. Juveniles have been observed picking algae off submerged rocks. Feeds on algae. Occurs sympatrically with (and possibly mistaken for) Puntius sp. 'martenstyn' throughout the known range. May be greatly endangered by the damming of Mahawel River. Too rare and difficult to capture for food.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00317 - 0.01581), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
