55 Gallon Tank Silver Dollar

A friend at work is having problems with her silver dollar. He's had these black spots for at least 3 years, but they've recently grown larger and she's concerned. The spot closest to the tail has starting rising away from the body a little bit.

I've attached pics. Can anyone help identify if anything's wrong or if it's just natural for him?

Thanks, everyone!

same thing happened to one of ours at work and the holes went straight thru him after a few days
I had never seen it and one of the girls bought E.M. Erythromycin on my day off and treated him...although hes better, the scars are still there....I still don't know what it was/is to cause this....

Thanks, Shawnie! I wasn't able to look for Erythromycin this weekend for her, but would Maracyn Plus be okay? Or should she wait until I find the Erythromycin? She can get her cycle back quickly with any meds. I have plenty of media I can share with her to help.

Do we need to separate him to treat him? I could set up a quarantine "bucket" for him here if I need to. Or I could print out the "quick and dirty quarantine setup" information for her. If he has scars, it won't bother her. She just wants to know how to help him.

Thanks, Shawnie. I think I'll get my hands on the Erythromycin and give her the information on setting up a quarantine tank. If she's worried about it, she can bring him to me and I'll do it. I have plenty of extra bins that I could use or loan her one. They'll even hold a filter.

Good morning BB

I'm afraid I can't be of much help here either. Odd that the fish has had the spot for years. My Silver Dollars are spotted but they look nothing like what is in the photo. Too, the spots are not raised on mine.

Hopefully someone will come along that has experienced this same issue. If it's natural, I've never seen anything like it.

Best wishes!
Ken
