Water parameters
Overview
Cuming's barb is a small barb endemic to Sri Lanka. Its silver-gold body bears two dark vertical bands, one behind the gill cover and the other near the tail. Two natural color forms from different streams are known, one with red fins and one with yellow fins. Because its natural range is narrow, captive-bred fish should be preferred whenever possible.
Tank Setup
- At least 60 liters and 60 cm in length for a group of 6–10.
- 23–26°C; soft, slightly acidic water. Stable parameters are important.
- Densely planted edges, roots, a dark substrate and dim light with floating plants.
- A 20–25% weekly water change; gentle flow.
Diet
Omnivorous. It accepts small flakes and granules; frozen and live foods (brine shrimp, daphnia, small bloodworms) noticeably improve color and condition. Also provide plant matter with spirulina food.
Behavior and Compatibility
Peaceful and somewhat shy. Males display to each other by spreading their fins; this is harmless. It behaves more boldly in a large group and a planted setting.
Good companions: cherry barbs, harlequin rasboras, small tetras, corydoras, otocinclus, dwarf gouramis.
Avoid: active, dominant barbs such as the tiger barb, large or aggressive fish.
