Betta rutilans

Deep red throughout, without a separate flank spot or parallel gold gill-cover bars.

Deep red throughout, without a separate flank spot or parallel gold gill-cover bars. Pelvic fins are red with white filamentous tips.

Natural habitat: Inhabits heavily shaded peat swamp forest and connected blackwater streams, among fallen leaves and roots.

From blackwater habitats, it needs acidic water with low hardness and cover.

Social behaviour and territory

Prefer a single pair. Persistent aggression occurs in groups; small size does not justify crowded keeping.

Try suitably sized dry food, alternating with live or frozen foods such as Daphnia and brine shrimp. Feed small portions and avoid overfeeding.
