Checker Barb

Oliotius oligolepis (formerly Capoeta oligolepis) inhabits soft, slightly acidic streams in Sumatra and Borneo. Its common name derives from the alternating pattern of dark scale edges that create a checked appearance across the flanks. Males develop reddish fin colouration. A peaceful and easy-care species, it does best in soft, well-planted aquaria with moderate water movement and is often overlooked in favour of more boldly coloured barbs.

Water: 20–26°C, pH 6.0–7.5, soft to moderately hard (GH 4–12). Tank: 60 L minimum; well-planted with some open space; moderate filtration. Feeding: Omnivore; flake, micro-pellets, algae-based foods, and small frozen/live foods. Behaviour: Peaceful schooler; keep in groups of 6+; males may spar briefly. Compatibility: Excellent with small tetras, rasboras, corydoras, and other peaceful cyprinids.
