Carpenter wrasse acting strange along with fin damage

[Jstn]

Last week I brought home a large carpenter wrasse, he was healthy eating, ect. Tonight I get home and there is noticeable damage to his dorsal fin (it remains closed but I estimate 50% missing, noticeable flesh damage.), he wont eat and its way past his bed time yet he is still up.

He the largest fish I have, so there are no predator fish, not to mention the other fish never shown sings of being attacked (crab, worm ect.)

Any ideas?

How is the quailty of your water?

Perfect, nitrates 1ppm po4 0.05, everything looks heathy, I wonder if he got stuck under a rock and struggled to get out?

Before (last week)




Today the one side seems worst, it doesnt look like an infection, but its spreading like one.





Any ideas from the fish Drs?

what inverts in the tank? Was this fish quarantined?

Looks like a serious bacterial infection to me

Extremely blurry, but from the blur, I would agree that it appears bacterial.
