That copperband is almost black mark free. The spot faded so much it is hardly noticeable so now he can go out in public without having to explain what that was.
Here is that same copperband, totally cleared up. I have no idea what it was and I am sure the Copperband doesn't know either.
My copperband eating lunch. The paper thin pieces are his favorite and those are clams that I freeze and slice paper thin. I alternate the clams with worms. The rest of the food is LRS which he also loves.
