One of my chromis got his tail bite off.

[The Guy]

Ok so one of my beloved Oselara clowns decided this little chromis was too close to their pulsating exenia and well the poor little guy got his tail bite half off and today the other half fell off. He seems to swim ok and I think he's eating, I got some food with garlic in it to maybe help his emune system.
So should I just leave him in the tank and see if he makes it or? I tried to catch him but with a tank full of rock it's almost impossible to snag him out. I guess if it dies my bottom hermit's clean up crew will have meal, but I hope he makes it.
