I have no idea what to do. My fish has been sick lately, very lethargic and not wanting to eat. I got him some aquarium salt and I bought some stress coat today but when I got home from work he was standing straight up as close to the top of the tank as he can get. I don't know what to do. He will sink to the bottom like that as well. Head pointed toward the top of the tank. He has enough strength to propel himself up when he takes a breath and I have him resting on a leaf close to the surface of the water now. But I don't know what to do to make him better. I don't want him to die please help.
