I'm a little worried that some of my fish in one of my 40 gallon tanks has carp pox. I just added a new goldfish, so I'm worried that if the other fish do have carp pox, that he will get it. I'm not completely sure if it's just a slime coat irritation, or if it's carp pox. Some of the fish have some small white bumps and one of them has what looks like some irritation on one side.
