The GloFish is a trademarked brand of genetically modified fluorescent zebrafish with bright red, green, and orange fluorescent color. They are extraordinary, hardy, and beautiful!! Although not originally developed for the ornamental fish trade, it is the first genetically modified animal to become publicly available as a pet. They are very similar to other fish, but they have a much brighter disposition. Each new GloFish inherits it's unique color directly from its parents, maintains the color throughout its life, and passes the color along to its offspring.
