The GloFish is a patented and trademarked brand of genetically engineered 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 "Electric Green", "Sunburst Orange", "Moonrise Pink", "Starfire Red", "Cosmic Blue", and "Galactic Purple" colored tetra (Gymnocorymbus ternetzi), an "Electric Green" tiger barb (Puntius tetrazona) and a glo-Rainbow Shark (Epalzeorhynchos frenatum) have 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. It is sold only in the United States, where it remains the only genetically modified animal to be publicly available. The rights to GloFish are owned by Spectrum Brands, Inc., which purchased GloFish from Yorktown Technologies, the original developer of GloFish, in May 2017.
