securitas writes "It was bound to happen. Texas-based biotechnology company Yorktown Technologies will start selling a 'genetically engineered aquarium fish that glows in the dark.' The trademarked GloFish -- 'a tropical zebra fish infused with the gene of a sea anemone that makes it glow fluorescent red' -- is first genetically engineered pet. The possible consequences of introducing a new trangenic species into the environment has touched off a debate that has critics such as the National Academies of Science and the Center for Food Safety calling for a ban on the sale of the fish unless the FDA regulates and approves it. The fish go on sale in January 2004. You can see photos of the GloFish here. Cool, but it's no Blinky." M : I think these guys are marketing the fish for a Taiwanese company.
