Betta Brownorum
Betta brownorum
📍 Southeast Asia
Betta brownorum is a peaceful, mouth-brooding wild betta species native to Southeast Asia, making it a fascinating alternative to the aggressive Siamese fighting fish. Unlike their flashy domesticated cousins, these fish display subtle earth-tone coloration and exhibit complex social behaviors in properly sized groups. They are best suited for experienced aquarists who can provide appropriate tank conditions and understand their unique breeding behaviors.
Care Guide
Diet
Betta brownorum require small live foods such as microworms, daphnia, and small insects to thrive. Supplement with high-quality micropellets designed for small fish. Feed small portions 2-3 times daily, as their tiny mouths require appropriately sized food. Live food is essential for conditioning breeding pairs.
Behavior
These are peaceful, social bettas that can be kept in small groups or pairs, unlike their aggressive domesticated relatives. They are bottom-to-middle dwellers that spend time exploring substrate and vegetation. Males exhibit courtship displays and will mouth-brood fry, showing parental care behaviors rarely seen in aquarium bettas.
Breeding
Betta brownorum are mouth-brooders that require soft, acidic water and plenty of plants or caves for spawning sites. Breeding is moderately difficult and requires conditioning pairs on live food and maintaining stable water parameters. Males will incubate eggs and fry in their mouths for 10-14 days before releasing them.
