This is an old thread but I thought i would have a word in it so everyone has a heads up. Feeding goldfish is not good for pet consumption whatsoever. Inside goldfish, contains a growth-inhibiting enzyme called thiaminase(hoped i spelled right), which blocks intake of vitamin B and basically stunts the growth of your pet. You're much better off feeding minnows, even cichlids. Just remember, anything from the Carp family will contain thiaminase.
