Electric Green GLO Tiger Barb (Puntius tetrazona)

Tiger barbs bring their own reputation into the GloFish lineup, fast, boldly striped, and a known fin-nipper in small groups, all of which carries over unchanged under the added fluorescent-green glow. The heritable gene traces back to the same zebrafish pollution-biosensor research behind every GloFish color. Keep the group at six or more so that nipping energy stays directed within the school instead of at slower tankmates.

Care level: Easy · Temperament: Semi-aggressive, shoaling · Max size: ~3" · Min tank: 20 gal · Diet: Omnivore, flake/pellet
