I went to an Asian supermarket and I bought a package of frozen wild caught seafood. It has clams, squid, etc. It also has crab meat. My wife says it looks like imitation crab meat, but I'm not sure. She doesn't think I should feed fish this. I'm going to chop it all up together to feed. My question is, if the crab is indeed imitation, would it harm the fish, providing it is going to be chopped up with the rest of the seafood, or should I should I just take it out?
