I dont think the common goldfish has anything to do with grass carp though. Totally different species. Releasing aquarium fish into any water supply is far more dangerous than just the destruction that the particular fish may do to it's surroundings. If that aquarium fish had some sort of parasite or disease, it can wreck havoc in the water that it goes into. I know this is generally a problem with fish sold for very cheap but become massive in size. Most notably, the common goldfish (comet goldfish) and the common plecostomus.

Well they were bred from common carp. If they were allowed to breed freely then they would very quickly revert back to being just that, carps. If you're referring to the common goldfish and comet goldfish then they came from asian carps. Without breeders to cull the ones reverting back to carps, each generation would just bring them one step closer to being carps again. Just food for thought.
