Greetings. I think my pet minnow may have swim bladder. He is floating at the top upside down, but breathing and trying to move, so we are going to not feed him for three days and feed him peas like I've read. What bothers me is how hard and labored his breathing is. Is that normal for fish with swim bladder...or is he suffering? If he is suffering, I don't want him to stay that way. Thank you.
