Opsarius bakeri

Opsarius bakeri is a slender and active freshwater fish native to the clear streams and rivers of the Western Ghats in southern India, where it inhabits well-oxygenated waters with steady current and open swimming space. Its streamlined body, lively shoaling behavior, and bluish markings along the flanks give it a refined hill-stream character that is especially attractive in aquaria designed to emphasize movement and natural riverine conditions. When keeping this species, providing strong filtration, clean oxygen-rich water, ample horizontal space, and a group-based environment is important for reducing stress and allowing the natural agility and social behavior of this distinctive danionid fish to be fully appreciated.
