Betta channoides Breeding Guide

Breeding the Snakehead Betta Betta channoides: a Bornean paternal mouthbrooder with a 10-21 day oral incubation, covering sexing and fry care.

Overview

Betta channoides, the Snakehead Betta, is a paternal mouthbrooder from the Mahakam river basin of East Kalimantan, Borneo, where it inhabits shallow forest streams with brownish, acidic water among leaf litter and marginal plant roots. The male incubates the eggs and fry orally.

Sexing

Adult males are more colourful and have a broader head shape than females. The broader head accommodates the developing brood during mouthbrooding.

Breeding Setup

• Temperature: 23-30 C
• pH: 4.0-6.5
• Hardness: 18-90 ppm (soft, acidic water)
• Brownish, tannin-stained water with leaf litter and cover

Recreating shallow, acidic forest-stream conditions with leaf litter and shaded cover supports natural courtship and spawning.

Spawning Behavior & Trigger

Following courtship the pair embrace, with the male wrapping his body around the female. Eggs are caught on the male's anal fin, then the female picks them up and spits them back for the male to catch; this cycle repeats until spawning completes.

Egg & Fry Care

Brood size is quite small, with even 10 eggs being considered a good number. The incubation period is 10-21 days, after which free-swimming fry are released. Fry are large enough to accept motile foods such as microworm and Artemia nauplii immediately; provide small amounts of different foods 2-3 times per day, with regular small water changes preferred over large intermittent ones.

Common Challenges

Small broods mean numbers build slowly, and an inexperienced or disturbed male may release the brood prematurely. Keeping the holding male undisturbed in stable, soft acidic water is important.
