Genetically engineered angelfish (Pterophyllum) glow in a tank under a blacklight, at a fish farm in Pingtung, southern Taiwan, September 16, 2010. The fish are the world's first fluorescent angelfish which were created by a joint project between Taiwan Academia Sinica and Jy Lin, a private biotechnology company. The breed is the largest fluorescent fish in the world which are able to mate and reproduce, said Yu-Ho Lin, Chairman of Jy Lin. The fish are expected to be sold at around $30 after certification.
