Description

The Wild Betta splendens is the original, natural form of the popular Betta fish, also known as the Siamese Fighting Fish. Unlike the selectively bred domestic varieties with long, flowing fins and vibrant colors, the wild Betta splendens has a more streamlined body, shorter fins, and subtle yet beautiful earthy tones with flashes of blue, green, and bronze iridescence.

Native to the slow-moving waters of Southeast Asia—such as rice paddies, canals, and shaded streams—Wild Bettas are hardy and well-suited for blackwater setups or densely planted aquariums. They thrive in soft, slightly acidic water with minimal flow.

Males can be territorial, especially in confined spaces, so it's recommended to house a single male per tank unless breeding. A pair or trio in a well-structured tank with plenty of hiding spots and visual barriers is ideal.

These Bettas are bubble-nesters and show fascinating natural behaviors when breeding or claiming territory. Their diet should be protein-rich, consisting of small live or frozen foods such as daphnia, bloodworms, and brine shrimp.

The Wild Betta splendens is perfect for aquarists seeking an authentic, nature-inspired Betta experience. Its natural behavior, charm, and manageable size make it a standout addition to biotope or low-tech community aquariums.
