Lesion?

[alicia24]

Hi,
Sorry the picture/video quality is not great( they're in a bucket) I was transferring my fish from qt about to go into dt when I noticed my puffer has like a lesion near his tail. I'm assuming I nead to put all the fish back into qt? What else do I need to treat with? I already did copper, prazi, and kanaplex. Puffer seemed healthy other than swimming a little weird sometimes. Idk if this is a lesion from trauma from catching it.

This looks to be a physical injury and to prevent infection, I recommend immediate treatment using seachem Neoplex or kanaplex and assure it’s healing and not getting worse
