Asia: restricted to forest streams from the Kelani to Nilwala basins in Sri Lanka. It occurs in hilly areas up to about 300 m elevation. The brightly colored population introduced to Mahaweli at Ginigathena, Sri Lanka are said to have diminished in number due to the aquarium export trade.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 6398); 6.7 cm TL (female)

Inhabits clear, cool, shady streams in forested areas, on gravel or sand substrate. Sometimes found in pools of quiet water in the margins of clear streams and rivers (Ref. 6471). Bred in captivity. Spawns in shallow water among marginal weeds. Eggs (>100) hatch in 1-2 days; fry are free-swimming after 24 h (Ref. 6702). Feeds mainly on filamentous algae and detritus (Ref. 6703). Males brightly colored and with darker fins. Popular aquarium fish. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 80 cm (Ref. 51539).

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=0.01047 (0.00454 - 0.02413), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

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).
