The Betta Ocellata (Betta ocellata), known as the Eye-Spot Betta, is a large and striking wild Betta native to the clear, fast-flowing rivers and streams of Borneo — particularly Sabah, Malaysia, and Kalimantan, Indonesia. A paternal mouthbrooder, it is named for the distinctive ocellated (eye-spot) markings on its caudal fin. Its robust, elongated body displays rich brown and olive tones with vivid iridescent blue-green scaling and bold red fin colouration — a truly impressive species for the serious wild Betta keeper.Care Guide Tank Size: Minimum 120L per pair; species-only setup essential Water Parameters: pH 5.0–7.0 | Temp 22–26°C | Soft to moderately hard, well-oxygenated water; cooler temperatures preferred Diet: Carnivorous — live or frozen earthworms, bloodworm, and large invertebrates; readily accepts quality carnivore pellets Temperament: Males territorial; best kept as a single pair with ample space and visual breaks Tank Setup: Planted tank with large driftwood, smooth rocks, leaf litter, and moderate flow; replicates their natural river habitat Skill Level: Advanced Max Size: 13cm
