Sunburst Orange GLO Barb

This barb carries the heritable GloFish fluorescent gene tuned to a saturated electric orange, the same modification originally developed in zebrafish for pollution-biosensor work before it reached the pet trade. Barbs in general do best in real numbers, and the underlying species here keeps the family's active, sometimes nippy energy that settles down once the group's big enough. Six or more keeps that energy pointed within the school.
