is this illness, or injury?

Tailspot in the QT. I swear he didn't look like this at the fish store but he looked like this from the moment he came out of hiding after getting him home.

It's been two weeks now, he's been in Cupramine. Doesn't look much different after two weeks. Very active and eating well.

It looks more like injury to me, but I'm wondering why no improvement.

Looks like injury to me too. For some strange reason, any new fish I buy immediately find a place in the QT where they can get cut, ripped up, stuck, etc. I guess it's just Murphy's Law.
