Green GLO Zebra Danio (Danio rerio)

Zebra danios were the original GloFish species, the fluorescent-protein gene was engineered into Danio rerio specifically for pollution-biosensor research before the modification became a commercial pet in the early 2000s, so this green line is about as close to the source material as the lineup gets. All the same fast, hardy, restless energy as a wild-type zebra danio, just glowing under it.
