I don’t remember but it looks like the fin is slip a bit like it got bit? But overall mine was an awful pale color most of the time while in the small quarantine tank. And always hide. He was even alone and got HLLE. Same exact line on face. Watch the fins may need treatment for secondary infection. I’ve dealt with that a lot when my fish are stressed or got bit with agression. Turns into fin rot fast. I just lost a scopa last week that my Caribbean blue nipped on the fins and it turned to fin rot.

As long as no other infection you should be able to finish the copper and put into dt tank and it will be fine. I hope!
Here’s mine today showing off for me !
