Well, he's very healthy. His coloring is mainly black, his belly is not tan like it is in the first pic.
I looked at him real close today and all visible marks are gone. When I turn off his powerhead, he know's it's feeding time and he comes out like a little puppy.
He is doing great! I did a large water change in his tupperware bin just today, so if that has an ill effect, I'll kick myself.
But as it stands, he's very active and healthy.
Thanks for asking.
