Eel Kuhli Loach (Pangio anguillaris) Care Guide
Pangio anguillaris is a plain, eel-shaped kuhli loach from Southeast Asia, a peaceful nocturnal bottom-dweller that buries in soft substrate.

Overview
The Eel Kuhli Loach (Pangio anguillaris) is a slender, eel-shaped cobitid loach with a largely patternless greyish body; some populations show irregular dark spotting or lateral striping rather than the bands seen in other kuhli loaches. It is a peaceful, nocturnal species that spends much of its time buried in the substrate and often shelters in clusters with others at rest.
Taxonomy
- Family: Cobitidae
- Genus: Pangio
- Scientific name: Pangio anguillaris
Habitat
The species ranges widely across Southeast Asia, including the Kapuas basin of Borneo, the Batang Hari system of Sumatra, Peninsular Malaysia, the Chao Phraya in Thailand and the Mekong in Thailand, Laos, Cambodia and Vietnam. It lives in shallow, slow-moving stretches of streams and in calm habitats such as swamps, oxbows and backwaters with vegetation and soft substrates.
Tank requirements
- Minimum tank volume: 80 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 5.5-7.0
- GH: 1-8 °dGH
- Group size: 6 or more individuals
- Lifespan: 8-12 years
Diet
It is a carnivorous micropredator feeding on insect larvae and small crustaceans. In aquaria it accepts sinking dried foods plus live and frozen Daphnia, Artemia, bloodworm and microworms, fed about twice daily.
Compatibility
It is peaceful with other fishes, although it may consume eggs or very small fry. As a species that naturally occurs in large aggregations, it should be kept in a group of at least six. A soft substrate for burrowing and a well-fitted lid are recommended. Aggressive tankmates are best avoided.
Eel Kuhli Loach (Pangio anguillaris) Breeding Guide
Overview
The eel kuhli loach, Pangio anguillaris, is a plain, elongated cobitid. Seriously Fish gives a wide range across Indonesia (Borneo), Sumatra, Malaysia, Thailand, Laos, Cambodia and Vietnam, spanning the Kapuas, Batang Hari, Chao Phraya and Mekong basins, noting a patchy distribution that suggests additional undocumented populations.
Sexing
Seriously Fish reports that females are typically heavier-bodied and slightly larger than males, while males have a branched and thickened first pectoral-fin ray, with pectoral fins that are upturned and longer than the female's. In some populations mature males develop what appears to be a nuchal hump on the head.
Spawning Behavior & Trigger
In the wild, Seriously Fish states that spawning occurs in shallow water with abundant vegetation, though detailed breeding information remains limited. No reproducible aquarium trigger is documented, and the shallow vegetated spawning niche has not been replicated by hobbyists.
Common Challenges
Because there are no captive spawns on record, there is no established protocol for conditioning, triggering or raising fry of this species. Keepers interested in breeding can only attempt to approximate the natural shallow, heavily vegetated spawning habitat.
