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.
