OP should have defined "real" and "fake". It seems that most people (maybe all people) who chose "real" just meant that the fish was real, not that it was actually a 30lb goldfish, but I chose "fake" since it is not a 30lb goldfish.
I remember seeing a Carp that was at least three or four feet long at Bush Gardens Willismburg VA and it was in a large man made lake and had come up into the shallows to feed but it was grayish sliver or graylish black but it was most likely as big as this or bigger but I don't think these fish come in Orange Like this though.
