So far what i believe i determined is he has swim bladder. He can swim to the bottom but floats right up once he stops. Also looks like hes breathing harder. Hes currently isolated from the rest of the tank. He also wont eat. I tried what hes been eating and also shrimp. Its been a few days since i noticed so hes done past fasting. Today i noticed hes not using one of his front fins. I dont know if its related or not. Is there anything i can do or is he a goner? His other tank mates are fine and doing well.
