Breeding Fish as Food

[McMonty]

Are there any types of fish available from the petstore that could be bred to be fed to snakes? I know rodents contain just about all the goodies your average snake needs, but isn't it good to supplement their diet with something different every now and then? Breeding mice and rats to feed them has it's downsides eg the smell and the possibility of escape. (If your fish escape - they aren't going to get very far). So what type of snakes can eat which kind of fish?
