Etymology: Puntius: Lantin, punctum = point, the point of the sword (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 6.0 - 8.0; dH range: 5 - 19. Tropical; 23°C - 27°C (Ref. 30491); 8°N - 6°N
Asia: Kelani to Nilwala basins, Sri Lanka. The more colorful varieties are possibly being overfished for the aquarium trade.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL male/unsexed; (Ref. 4832); common length : 2.5 cm TL male/unsexed; (Ref. 6028)
Occurs mainly in heavily shaded streams and rivulets, preferring shallow, slow-flowing water with silt substrate and leaf debris. Omnivorous, the gut containing detritus, green algae, diatoms, dipterans and animal matter. About 200 eggs are scattered among marginal plants. Young hatch in 1-2 days and are free-swimming after 48 hours. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00544 - 0.02785), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tm<1, Fec=150-250).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
