Environment
A heated aquarium of at least 20 liters, planted and without strong current, suits it perfectly. Maintain water between 24 and 28 °C, pH 6.5 to 7.5; a heater is essential. Cover the tank as it can jump, and leave a free space at the surface so it can breathe air.
Feeding
Carnivorous, it prefers protein-rich foods: specific betta pellets, bloodworms, live or frozen brine shrimp and daphnia. Avoid overfeeding, its stomach is tiny. A weekly fasting day is beneficial.
Health & common diseases
The Betta is prone to fin diseases (bacterial rot), white spot disease (ichthyophthirius), fungal infections and dropsy. Watch for frayed fins, white spots on the body, swollen belly or raised scales. This species is particularly sensitive to temperature fluctuations and poor water quality; maintain a stable temperature (24-28°C), perform regular water changes and avoid overfeeding to prevent these diseases.
Tips & tankmates
Never keep two males together: they will fight to exhaustion. Ban the unheated bowl, a source of suffering and death. Also avoid tankmates with flowing fins or nippers, which cause stress and aggression.
