In spite of the odd sidebars contained in this thread, I do appreciate the overall point, which provided a bit of Glofish education. I am starting a new tropical tank with my kids for a summer fun project, and they saw a bunch of Glofish at our local Petsmart (USA) and got excited. I told the kids I didn't want to purchase any fish that were injected with colors, and had not ever seen this type before. But, apparently, they are bred from genetically modified parent stock, so I suppose I won't object to buying a few of these for the tank! And, no, I'm not planning on releasing any to my local river or lakes...thanks for the information!
