Hello Friends!

I have a 80 gallons i.e. 303 liters of Acrylic tank (SOBO Imported 5 feet tank). I have 2 Red Belly Pacu's with Parrot and Oscars. One day i noticed that the small Pacu have got some serious fin rot, possibly of bullying. I removed the Pacu and kept it into a hospital tank and treated my Pacu. My Pacu recovered well and all fins are back. But while in hospital tank he hardly eats anything and he kept on swimming in one corner of the tank.. I tried to put my recovered pacu back in the main tank. But the moment i put her back other fish attacked on him.. I tried to keep for some more time but other fishes were trying to eat him.. I immediately took him out and put him back into the hospital tank.. He seems very much afraid and don't eat anything..

Please help what to do....???
