Hi guys, I posted this on another forum but figured I would get the advice of our resident experts as well. This fish is new to me. It was introduced into my tank 5 days ago. He's been eating voraciously, both the mysis I've been feeding 3 times per day as well as pellet food. Today, large spots appeared on one side of his body. Are these spots from a disease, aggression from another fish, or abrasion from possible panicking in rock work? My complete neophyte analysis is that it looks like an injury more than an illness. I does not appear to be anything like the symptoms I've read about for ich. You can see that one side is ok, but the other side doesn't look so good.
