I have mixed feelings about glofish. Humans have been selectively breeding fish for decades, and while some people despise this, i don't have a problem with it provided the inbreeding is not so extreme that it creates health problems for the fish. Now, glofish were created in a lab, i beleive a jellyfish gene was spliced in to make them glow in the UV, which i must admit, would be really cool with the proper light setup. This is similiar to selective breeding, but with several important differences, the main being that there is absolutely no way that a jellyfish could ~ever~ cross with a danio. I have concerns that scientists are playing around with the genome that they don't even really understand yet, and that there could be unforeseen consequences to this sort of meddling. Maybe i should have never read Jurassic Park lol.
