Potaro Cory

Corydoras potaroensis is endemic to the Potaro River system in Guyana — a river famous among aquarists as the habitat of the Potaro River stingray and other Guiana Shield endemics. It is a modestly sized cory with a warm buff body traversed by a dark mid-lateral band from the humeral region to the caudal peduncle. Golden or brassy highlights are visible across the dorsal surface under bright lighting.

As a Guiana Shield species, it naturally inhabits soft, slightly acidic, tannin-stained rivers and streams. In the aquarium it performs best in similar conditions, though it will adapt to slightly harder water if changes are made gradually. Good water quality and a stable environment are essential for long-term health.

C. potaroensis is sporadically available through specialist importers and is primarily of interest to dedicated Corydoras collectors. It is peaceful, social, and undemanding in temperament, and will integrate seamlessly into any community tank of appropriate size and water parameters.

Water: Soft and slightly acidic, pH 5.8–7.0, temperature 22–26°C; Guiana Shield water chemistry preferred. Tank: 80 L with fine sand, leaf litter, driftwood, and subdued lighting. Feeding: Sinking pellets, frozen bloodworm, and Daphnia; variety is important. Breeding: Rarely bred; soft water and live food conditioning likely necessary. Compatibility: Peaceful with all Guiana Shield community species; ideal for specialist softwater biotopes.
