Green Tiger Barb

Green Tiger Barb (Puntigrus tetrazona) is a color variant in which the golden-orange body color is replaced by a rich, iridescent green to teal — a metallic sheen that shifts between olive-green and emerald depending on the light angle. The four black bars are retained, creating a fish with genuinely unusual and striking coloration. The Tiger Barb is an active, bold, highly social schooling fish with an unmistakable personality — constantly in motion, endlessly interacting with tankmates, and spectacular in a large group. It is one of the most recognizable aquarium fish in the world, kept by hobbyists for over a century.

Feeding & Care Tip: Hikari Micro Pellets and Sera Vipan Tropical Flakes make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Bloodworms or Hikari Vibra Bites to maintain the vivid coloration. Hikari Frozen or Freeze-Dried Baby Brine Shrimp are an excellent additional treat. Feed small amounts 2–3 times daily.

⚠ Fin-Nipping Warning: Tiger Barbs are well-known fin-nippers that will shred the flowing fins of angelfish, bettas, gouramis, and other long-finned species. Never keep Tiger Barbs with long-finned tankmates. The most effective solution is numbers — a group of 8 or more Tiger Barbs redirects aggression inward toward their own schooling hierarchy, dramatically reducing fin-nipping toward other species. A group of 4–5 is the worst scenario: too small to form a proper hierarchy, with excess energy directed outward. Go big with this species — 10 or more is ideal.

Native to the island of Borneo and the Malay Peninsula in clear, shallow, moderately fast-flowing streams with sandy substrate and patches of vegetation. In the aquarium, a well-planted tank with open swimming space and good filtration suits this active species well. Tiger Barbs prefer slightly soft, slightly acidic to neutral water, though captive-bred fish adapt to a wide range of conditions.

Keep in groups of eight or more — this is the single most important rule for Tiger Barbs. In large groups, Tiger Barbs direct their considerable energy and social aggression inward — males constantly chase, display, and establish hierarchy among themselves, leaving other species largely alone. In groups of four or fewer, that energy gets directed outward and fin-nipping of tankmates becomes a serious problem. Ten or more is ideal. Good tankmates in a large group include other robust, fast-moving fish — larger tetras, Corydoras, danios. Never keep with angelfish, bettas, or any long-finned species.

Tiger Barbs are egg-scatterers that spawn readily in the aquarium. A separate breeding tank with fine-leaved plants or a spawning mop, slightly warmer water, and the removal of adults after spawning gives eggs the best chance of survival. Fry are initially tiny and require infusoria or very fine dry food before graduating to baby brine shrimp.
