Natural habitat

Betta raja inhabits lowland swamp forests, specifically in freshwater environments that are benthopelagic. These regions are tropical, providing an ample source of organic material and cover essential for their lifestyle.

Where they are found

Their varying colors and fin types have resulted from selective breeding practices, leading to the diverse varieties available today.

Aquarium care

Provide at least a 19-liter tank with a gentle filter to maintain water quality. Regular water changes of about 25% weekly help keep the environment clean. Adding live or silk plants offers hiding spots which support their natural behaviors and comfort.

Feeding

Betta raja is an omnivore, requiring a balanced diet of high-quality flakes, pellets, and occasional live or frozen food items such as brine shrimp or daphnia for optimal health.

Compatibility

Male Betta fish should not be kept together due to their aggressive nature. Females can sometimes be kept in groups (sororities) but require careful introduction and sufficient tank space to minimize conflict.

Breeding

Betta breeding requires a separate breeding tank with warm, clean water and hidden spaces. The male will build a bubble nest and court the female. After spawning, remove the female to avoid aggression, and the male will care for the eggs until they hatch.
