I went to my dads house for 2 days and when I came my coral beauty was almost bullied to death. he IS IN SO BAD condition and I really need help. His fins are shredded by his main problem is his swim bladder! Right now he’s being held in a 5 1/2 gallon tank with nothing in it with hopes to get him back to health. What can I do for a swim bladder and buoyancy as well as the aggression between the two fish. Any help would be greatly greatly appreciated. I also want to note that I am only a teen who love the reef hobby but I don’t have the money to replace him and I love this specific fish. Thank for the help!
