And I have to disagree with Zsandman, they aren't dyed, they're modified in their genes, no physical harm is done. It'd be no different than a scientist adding a gene to Zsandman to give him a humped back like a camel and a blowhole like a dolphin, sure he'll be horribly disfiguring to look at, never be socially accepted, probably never loved by a woman either even if he paid her but technically no harm done. Besides I think this opens doors to really cool stuff, imagine marine sharks that can be kept in freshwater or modified to be freshwater and maybe the size of a molly or something. How cool would that be?
I mean a great white shark you can keep in your 55 gallon, what do ya feed it? well the mollie side can be fed flakes or you can get frozen mice , those will work or even a 3 week old kitten you might have lyin' around will do.
The possibilities are endless!
