Natural habitat
Betta ideii is typically found in the rivers and streams of Borneo, preferring environments with soft and slightly acidic water. It thrives in well-maintained tanks with suitable filtration, as cleanliness is essential for their health.
Where they are found
Betta splendens is indigenous to a variety of freshwater habitats across Thailand, Cambodia, Vietnam, and Laos. Often, these fish are found in areas with dense vegetation that offer both shelter and breeding opportunities.
Aquarium care
To ensure healthy growth and breeding, Betta ideii requires a tank of at least 20 gallons with good water quality and filtration. A temperature range of 21 to 24 °C is optimal, and it is crucial to maintain stable water parameters. Regular water changes are important to keep the environment clean.
Feeding
Offer a diet rich in protein suited for carnivorous fish, including high-quality Betta pellets and occasional live or frozen foods such as brine shrimp or bloodworms. Feed once or twice daily, providing only as much as they can consume in a few minutes. Remove any uneaten food to maintain water quality.
Compatibility
While Betta fish can live harmoniously with certain species, they are primarily territorial and should not be housed with other males. Female Bettas may coexist in groups if kept in a large enough tank, but monitoring is essential to prevent aggression.
Breeding
Betta ideii is a paternal mouthbrooder, where the male incubates the fertilized eggs in his mouth for 13 to 18 days, with 14 days being typical. Females usually initiate the spawning process. Proper water conditions and a quiet environment will encourage successful breeding.
