似鳢搏鱼 · Snakehead Betta

Overview

Displaying males of Betta channoides are scarlet, with an almost wholly red dorsal fin bordered narrowly in white. This small paternal mouthbrooder suits a quiet aquarium with very soft acidic water. Its modest broods and sensitivity to disturbance make restrained management especially valuable during incubation.

Distribution & habitat

It comes from the Mahakam drainage in East Kalimantan, Indonesian Borneo. Collectors often retain labels for individual localities. Fish inhabit shallow forest streams with brownish acidic water, sheltering among marginal roots and fallen leaves.

Aquarium setup

Create shaded retreats with wood, roots, pots, or pipes. Leaves add cover and microorganisms; subdued lighting and floating vegetation strengthen the sense of security. Maintain acidic, very soft water with low carbonate hardness and mild filtration. Fit the lid closely to prevent jumping while leaving humid air above the surface.

Diet & feeding

Probable natural foods include insects, small invertebrates, and zooplankton. Dry products are often accepted after acclimation, but offer regular live or frozen water fleas, brine shrimp, and bloodworms. Avoid overfeeding.

Behaviour & compatibility

Pairs and small groups can be kept in a species aquarium. Any companions should be tiny, quiet, and suited to the same water conditions. Larger or vigorous feeders can intimidate it or intercept food.

Sexual dimorphism

Mature males are more colorful and possess a broader head.

Breeding

Long courtship and practice embraces may precede laying. Eggs held briefly against the male's anal fin are gathered by the female and passed to him for incubation. Ten eggs already constitute a worthwhile brood. Stress or inexperience can cause premature swallowing or release, so leaving the female and established companions undisturbed is preferable during brooding.

After approximately ten to twenty-one days, free-swimming young emerge. They can be transferred for rearing or usually remain safely with adults. Microworms and brine shrimp nauplii are accepted immediately. Give small, varied meals several times daily without excessive reliance on brine shrimp. Tight cover maintains the warm, humid air needed by developing fry; regular small water changes limit disruption.

Notes

Narrow dorsal-fin edging and a dark tail band that stops short of the uppermost portion distinguish it from a close look-alike. Combine fin details with locality information rather than relying only on the intensity of red coloration.
