Most people have trouble not stuffing their face and gaining a few extra pounds on chocolate. But have you ever heard of a fish with the same problem? Apparently the fish outgrew its tank, getting fed a daily diet of Kit Kat bars.
Aquarium staff were baffled when the 8.8lb giant gourami called Gary rejected normal food after being donated to them.
Then the previous owners of the exotic Asian freshwater fish admitted feeding it only with the chocolate-covered wafers.
Experts at the Sea Life London Aquarium had to put crushed Kit Kat pieces inside grapes and banana slices to tempt the 15.7in-long fish on to a normal diet.
Gary's handler Rebecca Carter said: "I've never heard of a fish being fed chocolate, let alone brought up entirely on the stuff."
