Swim bladder problem after trauma

[JBS92]

My clownfish started fighting and one of them took a pretty extensive beating. Half of its tail is missing, the anal fin is practically gone, and definitely scale damage. I have separated them and it seems to have gotten a bit more active than it was yesterday.
I noticed though that it swims at the top of the tank and will randomly turn on its side or will be vertical.
I guess my question is 1) will this stop happening as the fish heals?
2) can I ever safely put this clownfish back with its tank mate or will it get just continue to get attacked?

im so sad for this fish. A month of getting along and then aggression from the other fish out of nowhere

they likely will not get along. that clowns in rough shape. Might be save-able if its still eating. Needs to be in a safe place though, maybe with some antibiotics
