Blue Red Plakat Betta (Betta splendens) is a domestic form of a Southeast Asian freshwater species native to Thailand, Cambodia, Laos, and Vietnam, where wild bettas inhabit shallow wetlands, rice paddies, floodplains, canals, and slow-moving vegetated waters.

This variety has the compact short-fin structure of a plakat betta, with strong swimming ability, a broad body profile, and bold blue-and-red coloration produced through selective breeding. Like other bettas, it has a labyrinth organ that allows it to breathe atmospheric air in warm, low-oxygen environments.

Blue Red Plakat Bettas are valued as individual freshwater show fish with intense color, active movement, and a more athletic appearance than long-fin forms. Their domestic color pattern is selectively bred, while their territorial display behavior remains tied to the natural instincts of the species.
