Care guide
Betta channoides, commonly known as the Snakehead Betta, is a small paternal mouthbrooding labyrinth fish native to blackwater environments in eastern Borneo, Indonesia. Adults reach a standard length of 3.5–4.0 cm and are best maintained in a species-only or carefully selected community tank with a base of at least 45 × 30 cm. The species requires soft, acidic water with a pH of 4.0–6.5, temperatures of 23–30 °C, and negligible carbonate hardness. The aquarium should be furnished with driftwood roots, dried leaf litter, and dim lighting to replicate its natural habitat of shallow forest streams. Floating vegetation and shade-providing plants such as Microsorum or Cryptocoryne are beneficial. Filtration should be gentle, with an air-powered sponge filter preferred. As a labyrinth fish, it requires access to a layer of humid air above the water surface, and the tank must be well-covered to prevent jumping. Its diet consists primarily of small live and frozen foods such as Daphnia, Artemia, and bloodworm, though dried foods may be accepted once the fish recognize them as edible. Betta channoides can be maintained singly, as a pair, or in a small group, where it displays interesting behavioural interactions. It is not recommended for a standard community setup, as larger or more vigorous tankmates may intimidate it. Compatible species include very small, peaceful cyprinids and loaches from similar blackwater habitats. Males are more colourful with a broader head shape than females. The species is a paternal mouthbrooder with a small brood size; even 10 eggs is considered a good number, and the incubation period lasts 10–21 days.
