First created by a partnership between Yorktown Technologies, Segrest Farms, and 5-D tropical, the GloFish is quickly becoming a home aquuarium staple. The organism's main selling point: the fish appear normal in regular light, but glow in neon colors when exposed to black light. How did they achieve this trait? The scientists in the partnership took the tropical zebra fish and paired it with green flourcent genes from jellyfish to create their green and yellow colored fish and the red flourcent genes from a sea anemone for their pink/red colored fish. These fish may seem like a silly use of GMO technology. However, these fish were desgined specifically for home aquarium use and have been becoming best sellers throughout the nation.
