Barbus tetrazona "Green Apple" – Green Apple Tiger Barb (3–3.5 inches)

The Green Apple Tiger Barb (Barbus tetrazona "Green Apple") is a colorful freshwater fish with a bright green-golden body, four distinctive black vertical stripes, and red-tipped fins. An active and playful schooling fish, it brings energy and visual appeal to community aquariums. While generally peaceful in groups, it may nip fins if kept in too small numbers or with long-finned tankmates.

Size

Adult length: ~3–3.5 inches (7–9 cm).

Lively, mid-level schooling swimmer.

Behavior & Social Needs

• Shoaling species: Keep in groups of at least 6–8, larger schools reduce fin-nipping and encourage natural behavior.

• Energetic and playful swimmers that thrive in planted community tanks.

• Compatible tankmates include other barbs, danios, and small tetras. Avoid slow or long-finned species like angelfish.

Tank Conditions

• Tank size: 20 gallons minimum for a proper school.

• Temperature: 74–80°F (23–27°C).

• pH: 6.5–7.5, neutral to slightly acidic preferred.

• Setup suggestions: Include plants, driftwood, and rocks for hiding spots, along with open swimming areas and moderate lighting to showcase colors.

Diet

Omnivorous: Accepts flakes, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms.

A varied diet enhances coloration and fin vibrancy.

Lifespan & Hardiness

• Hardy and suitable for beginner aquarists when kept in stable water conditions.
