Family: Cobitidae
A peaceful omnivore cobitidae from Southeast Asia (Java, Sumatra and Borneo, Indonesia) — beginner-friendly.
Pangio kuhlii of the family Cobitidae is an aquarium-kept Cobitidae. Peaceful and omnivore; quality prepared foods with variety, it grows to 8.4–12 cm and prefers 24–30 °C water. Other Pangio species in our database include Pangio oblonga, Pangio semicincta, Pangio shelfordii.
Yes — a classic starter among ornamental loaches. 24–30 °C, soft acidic water (pH 5.5–6.5), 120 L or more, and a group of 5 or more. Meet these and it lives 5+ years. What it fears isn't difficulty, it's loneliness.
It's nocturnal and bottom-dwelling — hiding in crevices is nature, not illness. To see more of it, plant densely, add driftwood caves, soften the light, and feed at dusk. You'll find it's very active. The first two weeks after arrival it hides even more; that's normal acclimation.
They come from blackwater streams in Java, Sumatra and Borneo, long adapted to low-mineral environments. In hard water their mucus secretion and gill function suffer — showing as whitish skin and flashing. Hard-water regions should blend with RO water or add Indian almond leaves.
Fine sand (0.5–1 mm) is the only right choice. It burrows through sand to forage; coarse or sharp gravel abrades the soft belly and lateral line. Lay 4–5 cm and you'll watch it dive in and out — the core joy of keeping kuhlis.
The name honors Dutch ichthyologist Pieter Kuhli; Chinese common names include snake-fish and kuli loach (early transliteration). Its eel-like banded body of yellow and black rings makes it the most recognizable ornamental loach.
Adult cherry and crystal shrimp are safe, but shrimplets get eaten. If your tank's purpose is shrimp breeding, skip the kuhli; if fish are the focus, it's an excellent bottom cleaner that scavenges leftovers without attacking adult shrimp.
Omnivorous bottom-feeders: small sinking granules, bloodworms, brine shrimp and algae wafers all work. Vision is poor and foraging is by smell — slow-sinking or bottom foods are best, and avoid strong flow scattering the food.
Very — home spawning is rare. It demands very soft acidic water, seasonal water-level swings to stimulate, and live-food conditioning. Nearly all trade fish come from Southeast Asian farms; home breeding remains a challenge.
Adults reach 8–12 cm, thick and muscular. Lifespan runs 5–8 years — among the longevity champions of small bottom fish. A kuhli is a many-year companion, not a passing pet.
Jump rating is low, but escape through gaps is documented — it can exploit tiny openings with its flexible body. Cover the tank or at least seal pipe holes. More often it climbs out along heater cables when water levels drop, an accident rather than a leap.
