Green Tiger Barb

The Green Tiger Barb is a color morph of the Sumatra Barb, a widely kept cyprinid native to Sumatra, Borneo, and parts of the Malay Peninsula. It shares the same bold black-banded pattern as the standard orange Tiger Barb but displays a moss-green to olive body tone instead of orange-red. This variant arose through selective line-breeding within the aquarium trade rather than occurring commonly in the wild. It has become a popular alternative for hobbyists seeking variety within the tiger barb group while retaining the species' characteristic energetic schooling behavior. Wild-type populations remain widespread and are not considered threatened.

The Green Tiger Barb shares the deep, diamond-shaped body of the standard Tiger Barb, reaching 5-7 cm.

• Body color: Olive-green to mossy green base rather than orange
• Bands: Four bold black vertical bars crossing the body and through the eye
• Fins: Dorsal and pelvic fins often show red-orange tips
• Shape: Deep-bodied, laterally compressed, with a forked tail

It is distinguished from the standard Tiger Barb primarily by its green body tone; the banding pattern, fin shape, and overall proportions are otherwise identical.

In its wild ancestral form, this species inhabits slow-moving streams, tributaries, and forest-edge waters across Sumatra, Borneo, and the Malay Peninsula. It favors well-vegetated, shaded waterways with soft, slightly acidic to neutral water and moderate to warm tropical temperatures. These habitats typically feature submerged branches, leaf litter, and overhanging riparian vegetation that provide cover and feeding grounds. As a hardy, adaptable species, it tolerates a range of water conditions and is often found in both blackwater and clearwater tributary systems. The green color form is exclusively a product of aquarium breeding and is not found in wild populations.

Green Tiger Barbs are active, energetic schooling fish that display pronounced hierarchical and nipping behavior, particularly when kept in insufficient group numbers. In larger shoals of six or more, aggression is diffused among the group and fin-nipping toward other species is reduced. They are omnivorous, foraging on small invertebrates, algae, and plant matter throughout the day in the middle to lower water column. Spawning follows an egg-scattering strategy, with adults releasing eggs among fine vegetation and showing no parental care. Their constant motion and inquisitive foraging make them conspicuous, active members of a community aquarium.
