Not even passing judgement on the morals of geneticaly altering animals, why would scientists rely on fish to tell them that water is polluted, you would think that we would already have a test or known reagent that would do the job without putting an extra animal in harms way.
So i was poking around on their web page and there is a note that breeding in prohibited due to "licensing restrictions". People will try to license anything these days. Not to be overly critical of the practice of licensing but if an animal is going to breed, its going to breed.
You guys are right. They aren't dyed. They are genetically altered. What they did was take out one chromomzone and put in a jellyfish chromozone to make it glow like that. I have a 50g. tank with alot of guppies. What I want to do is get a bunch of the glofish and let them breed in the 50g. I want to put a black light on them sometimes and watch them glow.
But originally I do believe they were zebra danios before they were altered. I also heard there going to be coming out with blue ones too. And I would much rather have one of these then a glass fish. From what I understand they inject the dye into the spine of the fish. That seems painful.
O.k I found out that they take out of the jelly fish is a bioluminescent protein. They then injected it into the zebra danio eggs. They don't have to inject everyone obviously. the parents will pass down the gene. I agree using them for pollution is kind of ridiculous, but then again if you think about it, if your lake is polluted all you have to do is look at the fish. If there glowing then you'll know theres something wrong with your water. So, in a way i guess i think it's kind of a good idea. As long as it doesn't hurt the fish.
