Betta Miniopinna 2-3cm
Betta miniopinna is a rare and delicate wild betta species native to the acidic blackwater peat swamps of Bintan Island, Indonesia. True to its name, meaning “small fin,” it features compact fins and a slender body, usually brownish with subtle reddish hues and iridescent highlights, especially in males. Reaching only around 3–4 cm in length, it thrives in soft, acidic water (pH 4.0–5.5, 24–27 °C) and heavily planted, dimly lit aquaria with leaf litter and tannins. A paternal mouthbrooder, B. miniopinna is best kept in pairs or species-only setups, making it a fascinating choice for advanced keepers of wild bettas.
