Its scary, but they say they use natural occuring genes and add them to the eggs before hatching. Its kind of like cross-breeding coral with zebra danios. Weird! I dont know, I guess it isnt hurting the fish, but I dont agree with it. Its along the lines of 'dying' fish. Keep it natural!
I just got done reading that before I signed in here... I guess I should be opposed to that sort of thing, but hey, if they look that cool in the tank... Yeah, I'd buy'em.
I think there are plenty of interesting and beautiful fish in freshwater and saltwater, so I don't think it's necessary to make 'new' fish. I don't think it's unethical, just not necessary. They've been doing it to food for years.
Yeah, there is a risk of them getting into the wild and contaminating the natural gene pool, but it's probably pretty slim. I never thought of calling it that though .
