Barbus tetrazona “Green” (Green Tiger Barb) – ~2.5–3 inches

The Green Tiger Barb is a captivating color morph of the classic Tiger Barb, displaying a striking jade-green body overlaid with bold black vertical stripes. It’s an active, spirited fish that adds vibrant motion and contrast to freshwater aquariums.

Care Guidelines:

• Temperament: Semi-aggressive and very lively. Best kept in larger groups to minimize aggression and fin-nipping.

• Schooling Needs: Maintain schools of 6 or more, though groups of 10 or more are ideal to spread out social interactions and energy.

• Tank Size: Minimum 20 gallons for a small school; larger setups (~30 gallons) are preferable to accommodate their swimming activity.

• Water Conditions:

  • Temperature: 72–79 °F (22–26 °C)

  • pH: Head toward 6.0–7.5

  • Hardness: Soft to moderately hard water

• Aquascaping: Provide open swimming space, with plant cover or décor at the tank edges. Use fine gravel or sand as substrate. Robust filtration and proper oxygenation support their high activity levels.

• Lighting & Décor: Moderate lighting enhances their vivid coloration. Include hiding areas using live plants, driftwood, or rocks to reduce stress.

• Feeding: Omnivorous. Offer quality flakes or pellets, with supplements of live or frozen foods like brine shrimp, bloodworms, or daphnia. A varied diet supports their health and coloration.

• Lifespan: With attentive care, they tend to live around 5–7 years.

• Compatibility: Best paired with other swift, equally sized fish. Avoid slow-moving or long-finned tankmates, which are prone to nipping.
