Was browsing at one of my on line fish suppliers, and now there are glo orange Cory’s…. A while back, there was a thread about dyed Arrowanas… what’s next glo angels???

Believe it or not Glofish weren’t originally meant for the trade. The first attempts to create them used Zebra Danios (Danio rerio) as the model organism. Researchers in Singapore were hoping to create fish that would fluoresce (glow) when water pollution was present.
However the first step in the process was perfecting the genetic transfer and visible glow. The scientists opted to insert green fluorescent proteins from marine jellyfish into the Zebra Danio genome.
And it worked! In fact, the resulting fish glowed under both normal and ultraviolet (black) lights. Other genes from corals and anemones carrying red, purple, and yellow proteins were eventually inserted, resulting in a riot of colors never before seen in Zebra Danios.
True!The EU bans glofish outright, and so they should. The hobby scientific side does not approve of modified fish whatever they are. The only way to stop this nonsense is not to buy them. Those developing/selling them are making money, and care nothing for the rest of it. All this effort and money should be spent to save the natural habitats and species. And the hobby, since this only adds fuel to the fire of animal rights organizations.
