Keep a group and let pairs form.
60 L soft acidic tank with leaf-litter and cover.
Soft acidic water and live foods.
Small broods: about 10 eggs is considered a good number. The male broods them for 10-21 days, then releases fully formed, free-swimming fry.
The male releases well-developed fry; feed baby brine shrimp.

The story of the channoides betta
A small mouthbrooding betta from the Mahakam basin in East Kalimantan, Borneo. Its name comes from the snakeheads (Channa), which have a similar head shape; displaying males are scarlet. It lives in shallow forest streams with brown, acidic water.
Kottelat and Ng described this betta in 1994, naming it for its resemblance to a snakehead. Its red colour and bold shape made it a popular wild betta.
First described by Maurice Kottelat & Peter K. L. Ng in 1994. Named for 'Channoides' means snakehead-like.
- Males brood eggs in their mouths.
- Its body shape resembles a small snakehead.
- It is closely related to Betta albimarginata.
