EXPERIENCE THE GLO: GloFish fluorescent fish and products create a complete underwater fluorescent experience. From the manufacturer Glofish While fluorescent fish do occur naturally in the environment, these GloFish were selectively bred by scientists to exhibit fluorescent colors throughout their life spans. They did this by introducing a natural fluorescence gene to ordinary Zebra Danios, and this gene then passed on to their offspring. These fluorescent fish were initially used to detect pollutants in waterways, but they soon became very popular among the public and have been sold in the United States ever since. Glofish Aquarium Kit Decor Lighting GloFish fluorescent fish are exclusively licensed by GloFish LLC. The GloFish Brand was founded in 2001 by Alan Blake and Richard Crockett with the goal of providing the first ever fluorescent fish to the aquarium market. In late 2003, after two and a half years of extensive environmental research and consultation with various Federal and State agencies, as well as leading experts in the field of risk assessment, GloFish caused quite a “splash” when they became available to the public. Since that time, we have worked tirelessly to make our fish available, and we have been proud to offer them to consumers across the United States.
