Help with Pajama Cardinal fins

[hoffmeyerz]

This kinda came out of the blue. He's acting normally and eating well but the fins progressed like this over just two days. The only thing different in the tank was adding a Falco Hawk that I had in qt. I'm not sure how to address it. My clowns can be aggressive and I've seen nips on him before but not like this.

This is not rot or fin ray damage but rather aggression and Pssst , , , see that innocent little clown in your video?

Set your phone on video mode for about 30 mins, feed the tank and walk away - MUST walk away and come back and review. You should see your culprit. Fish often show aggression during feeding to hog the food

He does look pretty beat up. I would try reshaping your rock work within the tank. It might change some of the behaviors and established territories of the fish. Are you able to put the PJ back into isolation to recover? some boosted food will help with his recovery.

Oh boy I think you hit that weight on the head! I've always seen some nips on the pj now and then but this was so drastic I didn't think it was aggression. I still have my qt running from the Falco hawk so I can throw him in there to recoup.
One of the reasons I picked up the hawkfish was it's bigger than the clown so the clown leaves it alone!
