It came from my local fish store here in Wichita Kansas. I've had the fish for over two years. I was subscribing to the immune philosophy regarding fish disease in fish health. About three months ago I placed all my fish in quarantine and allowed my display to be fallow. The regal tang pictured battled ICH off and on for those two years. Once placing her in copper the ICH went away and the symptoms you see in the photo began to appear after about a week and a half to two weeks. At first I thought it was maybe some kind of skin irritation related to the copper. I use both chelated and non-chelated forms with the same and result. I have been texting humblefish and the original poster on this forum for advice for the last month or so. When I would take the copper away the symptoms would get worse for me so I came to the conclusion that it had to be some kind of parasite. Also I noticed that after a freshwater dip some of the spots cleared and the fish rallied. Some of the other fish in my tank are from live aquaria so it's possible they were carrying the disease and once the regal things immune system dropped it spread to it in my opinion.
