Long story short I was gone for to days came back and my coral beauty angel fish is doing awful. He floats to the top and has lost almost complete control. My lemon tang wasn’t picking on him bad but I don’t know if it’s because he’s like this or if he was just picking on him. HOW do I help this fish because he dies or how can I help to neutralize/stabilize his swim bladder. He is greatly appreciate and need!
