The Green Tiger Barb, also known as the Green Barb or Green Tiger Barb Fish, is a vivid and energetic schooling fish that brings an intense metallic-green shine to freshwater aquariums. This selectively bred color morph of the Tiger Barb features a shimmering emerald body, bold dark stripes, and electric orange fins, creating a dramatic, eye-catching contrast in planted or aquascaped tanks. Originating from the tropical rivers of Southeast Asia, the Tiger Barb (Puntigrus tetrazona) has become one of the most popular Barb species in the hobby. The Green Tiger Barb is a selectively bred variation prized for its deep green iridescence that glows under aquarium lighting. Their energetic, playful behavior makes them favorite additions to community tanks that feature fast, robust species. When kept in proper groups, Green Tiger Barbs display beautiful schooling movements and bright, synchronized coloration. A full-grown Green Tiger Barb reaches about 2.5–3 inches (6–7.5 cm). Their body is covered in a rich, metallic green sheen layered over the classic Tiger Barb striping. Bright orange fins add a pop of vibrant color, making the Green Barb Fish a standout against green plants or darker substrates. Like all Tiger Barbs, the Green Tiger Barb is active, energetic, and semi-aggressive if not kept in proper numbers. They are happiest in groups of 8–10 or more, which channels their energy into natural schooling behavior and reduces fin-nipping. Ideal Green Tiger Barb tank mates include Danios, Rosy barbs & Cherry barbs, Rainbowfish, YoYo loaches, Corydoras, Larger tetras, and Plecos. Avoid long-finned or slow-moving fish such as Bettas, Angelfish, or Fancy guppies.
