Yeah, he does have a minor spinal deformity, shouldn't amount to any troubles though. Most of these babies are culls, we all have to remember that!
Looks like he'll be a DeT or possible HM/Super DeT with enough flare training. His anal fin is straighter on the bottom, if it were slanted then I'd be inclined to say VT since that's a VT trait. Dorsal fin isn't super pointed either (except for the protruding rays, as he grows, the membrane will catch up so he's not a CT) like a VT would be, so he's somewhere between DeT and HM
Fins too long to be PK as well.
EDIT: Oh and yes, he's a Black Copper.
