Southeast Asia – Indonesia
Schooling fish. Best kept in groups of 6 or more to reduce aggression and promote natural behavior.
Feed 2–3 times daily in small portions. Provide a varied diet of flakes, pellets, and live/frozen foods to maintain bright coloration and health.
Egg scatterer. Spawns over fine-leaved plants or spawning mops. Adults should be separated post-spawning to prevent egg predation.
Set up a separate breeding tank with soft, slightly acidic water (pH 6.0–6.5, temperature 78–82°F / 25–28°C). Provide spawning mops or fine-leaved plants. Eggs hatch in 24 hours, fry become free-swimming in 3–4 days. Feed fry infusoria or baby brine shrimp.
pH: 6.0–7.5, Temperature: 74–79°F (23–26°C), Hardness: 5–15 dGH, Ammonia/Nitrite: 0 ppm, Nitrate: <20 ppm.
Prone to ich, fin rot, and stress if water quality is poor or if kept in insufficient school sizes.
Semi-aggressive and active; best kept in schools to reduce fin-nipping.
Active, schooling, and semi-aggressive. Prefers mid-level swimming zones. Aggression decreases when kept in proper-sized groups.
Native to Southeast Asia, particularly Indonesia, the Green Tiger Barb is a hardy and visually striking variant of the common Tiger Barb. Best kept in schools of 6 or more to mitigate aggressive tendencies, it thrives in planted community tanks with open swimming areas and moderate water flow. Its bold green coloration and energetic behavior make it an attractive addition to any aquarium.
