The GloFish is a patented and trademarked brand of genetically modified (GM) fluorescent fish. A variety of different GloFish are currently on the market. Zebrafish were the first GloFish available in pet stores, and are now sold in bright red, green, orange-yellow, blue, and purple fluorescent colors. Recently an "Electric Green" colored tetra (Gymnocorymbus ternetzi) has been added to the lineup. Although not originally developed for the ornamental fish trade, it is one of the first genetically modified animals to become publicly available as a pet. The rights to GloFish are owned by Yorktown Technologies, the company that commercialized the fish.
