There are many fish in the hobby today that do not look like their wild counter parts, because we have tampered with them at one point or another. Look at the betta for one or the mickey mouse platy. The gold barb is said to be one of the few freshwater fish if caught in the wild that would look like the one in the hobby.
It seems that people either like them or they don't. I've noticed, they seem to really appeal to kids the most. They are pricey and I have seen that they don't seem as hardy as the regular zebra danios. At work the zebra danios are in one tank and the Glofish are in another tank and it seems that the Glofish will die more often then the zebra danios even though they are the same fish.
I don't see any problems if you bought Glofish and they bred. It becomes a problem if you try and sell them. If you go to the website they make it sound like they are sterile, but we know that to be untrue.
