Well ive had this issue with him for a while now. Seems to be months. Ive tried soaking his food, fasting him nothing seems to do the trick. He constantly has issues with his swim bladder. The other two fish i have (red oranda and ryukin) are just fine and have never had this issue. He doesnt float upside down all the time. Thats only when its really bad. When hes having issues his butt floats to the top and he cant seem to get his barrings. Swims irratically trying to fix himself. Is there anything i can do to help him get better?:(

He is in a 28 Gallon fish tank. Tank water is clear and the current isnt too strong. I have one large tall plant in the back corner of the tank with two smaller ornaments on the bottom
