Tiger Barbs (Puntigrus tetrazona) are lively, semi-aggressive freshwater fish known for their bold orange-and-black stripes, shoaling behavior, and fin-nipping tendencies. They thrive in groups of 6–10, live 5–7 years, and need at least a 20–30 gallon tank with warm, slightly acidic water.

🌍 Origins & Habitat

  • Native range: Sumatra, Borneo, Malay Peninsula.
  • Wild environment: Clear forest streams, peat swamps, and tributaries with sandy substrate, driftwood, and dense vegetation.
  • Water parameters in nature: 72–80°F (22–26°C), pH 6.0–6.8, soft to moderately hard water.

🎨 Appearance

  • Size: 2.5–3 inches (6.5–8 cm).
  • Colors: Classic orange-gold body with four vertical black stripes.
  • Variants: Green (moss), albino, platinum morphs — all behave identically.
  • Body type: Stocky, fast swimmers with bold shoaling behavior.

  • Moss Green Tiger Barb (Puntius tetrazona) 2-3cm

🐟 Behavior & Temperament

  • Semi-aggressive: Known for fin-nipping, especially if kept in small groups.
  • Shoaling species: Must be kept in schools of at least 6–8 to diffuse aggression.
  • Activity: Very active mid-water swimmers; they establish dominance hierarchies.

🛠️ Care Requirements

  • Tank size: Minimum 20 gallons for 6 fish; 30+ gallons recommended for 8–10.
  • Water temperature: 74–79°F (ideal ~76°F).
  • pH: 6.0–7.0.
  • Filtration: Moderate current with hang-on-back or canister filters.
  • Substrate: Sand or fine gravel; not fussy.
  • Aquascaping: Open swimming space with plants and driftwood.

🍽️ Diet

  • Omnivores: Accept flakes, pellets, live/frozen foods (bloodworms, daphnia, brine shrimp).
  • Feeding tip: Variety enhances color and health.
  • Schedule: 2–3 small feedings daily.

🧬 Breeding

  • Setup: Separate breeding tank with fine-leaved plants or spawning mops.
  • Method: Egg scatterers; parents do not guard eggs.
  • Care: Remove adults after spawning; fry need infusoria or micro foods initially.

⚠️ Risks & Challenges

  • Fin-nipping: Avoid housing with slow or long-finned fish (e.g., angelfish, bettas).
  • Stress/aggression: Too few barbs or small tanks increase hostility.
  • Health issues: Susceptible to ich, fin rot, velvet, and swim bladder problems if stressed.
