Red‑Line Torpedo Barbs are dynamic, peaceful schooling fish best kept in groups of six or more in a spacious, well‑oxygenated aquarium (55 gal / 200 L minimum) with moderate to strong water flow. They thrive in cool to moderate temperatures (~60–77 °F / 15–25 °C), slightly acidic to slightly alkaline water (pH 6.5–7.8), and medium to soft hardness. Their diet should be varied—high-quality flakes or pellets enhanced with carotenoids plus regular offerings of live or frozen foods like bloodworms, daphnia, and brine shrimp to keep their vivid coloration. Provide a fine gravel or sandy substrate, open swimming spaces, and some secure hiding spots with hardy plants, driftwood, or smooth rocks. They require exceptionally clean, oxygen-rich water, so powerful filtration, routine water changes, and a tight-fitting lid are essential.
