The tiger barb is one of the most vibrant schooling fish in the hobby and one of the most misunderstood. Their bold orange body with four vertical black stripes is instantly recognizable, but they have a reputation for fin nipping that deters many aquarists. The solution is simple: keep them in large enough schools. A group of 10 or more redirects all their energy into schooling behavior within the group — transforming a notorious bully into a dynamic, captivating centerpiece school.
Natural Habitat
Wild tiger barbs inhabit clear, fast-moving, oxygen-rich streams on Borneo and Sumatra. Water is warm, soft, and slightly acidic, flowing over rocky substrates. They school in large numbers in mid-water, feeding on insects, plant material, and small invertebrates.
Water Requirements
| Parameter | Ideal Range |
|---|---|
| Temperature | 74–82°F (23–28°C) |
| pH | 6.0–7.5 |
| Hardness (GH) | 4–15 dGH |
| Ammonia / Nitrite | 0 ppm |
| Nitrate | <20 ppm |
Tank Setup
A 30-gallon minimum for a school of 10; 40–55 gallons allows a more natural group of 15+. They prefer moderate to strong current. Green tiger barbs (melanistic), albino tiger barbs, and classic orange forms can all be mixed in the same school.
Diet
Omnivores. Quality tropical flakes or micro-pellets as staple; supplement with frozen bloodworms, daphnia, and brine shrimp 3–4 times weekly.
Compatible Tank Mates
Best with short-finned, robust fish: danios, barb species, larger corydoras, loaches. Strictly avoid: bettas, angelfish, guppies, long-finned tetras — their flowing fins are irresistible targets.
Common Health Issues
- Ich — raise temperature and treat with standard medication
- Fin rot — secondary to bite wounds or poor water quality
