71 days into fallow period. bacterial infection?

[Bpfor3]

i am 71 days into my fallow period. the only survivor was a marine betta that has been in QT the whole time. doing well and eating. Kept copper at 1.50 until 12/25 when i raised it to 2.0 ppm. just noticed that his left pectoral fin is torn and looks opaque. i think i should dose broad spectrum antibiotic before i put him back in DT. he is also in with a pair of long nose hawks that started the QT process about 30 days ago. never seen them pick on him, but i suppose its possible. Hawks look good.

Any thoughts appreciated.

If you see signs of infection then treat but if not, then I would let nature take its course.

They should be done with the copper soon though...no?

It looks ok, so i may just let it ride. Yes, doing 50% water change tomorrow and moving them back to the DT on Sunday. Thanks for the reply!

Congrats! Also, copper suppresses the immune system in fish so getting them out of the copper will help them recover quicker.
