Fiveband barb

The fiveband barb is a small, peaceful cyprinid from the blackwater peat swamps and forest streams of northwestern Borneo, with additional records from Sumatra and possibly Peninsular Malaysia. It is named for the five bold black vertical bars that adorn its golden-orange body — a pattern that closely resembles the tiger barb but with an additional fifth bar. Adults reach a modest 5.5 cm (2.2 inches), making them significantly smaller and notably more peaceful than their tiger barb cousins. They are true fin-nippers only when kept in insufficient groups; with proper numbers their peaceful nature shines through.

Unlike the semi-aggressive tiger barb, the fiveband barb is a genuinely peaceful community fish ideally suited to the softwater, acidic planted aquarium. It is a schooling species that requires groups of 8-10 individuals to display natural behaviour and optimal colouration. A tank of at least 72 litres with dim lighting, a dark substrate, driftwood roots, dried leaf litter, and dense planting that includes floating vegetation replicates its natural blackwater habitat. Peat filtration or the addition of Indian almond leaves will help maintain the soft, acidic conditions this species thrives in. They mix well with other small characins, rasboras, and Corydoras catfish from similar blackwater environments.

Water parameters: 21-26°C, pH 4.0-7.0, with very soft water (GH < 8 dGH). The diet should be predominantly small live and frozen foods — Daphnia, Artemia, Cyclops, and microworm — supplemented with high-quality micro-granules and finely crushed flake. Live foods are particularly important for maintaining the rich golden-orange body colour and encouraging breeding condition. They are egg-scatterers with no parental care, and breeding requires soft, acidic water with fine-leaved plants or a spawning mop. The fiveband barb is a hidden gem in the aquarium trade, offering the striking barred pattern of its more aggressive relative in a peaceful, manageable package suitable for the planted blackwater community aquarium.
