He's really not bloated all over. It really is only his abdomin. I've been given some advice that he may be constipated? That due to that stress, is why he is panting badly. I also had suggested to me that he may have eaten a juvinile Bristlenose and it has become stuck? I've noticed today that my yellow sucker catfish has a area which he has been rubbing. I've added some MelaFix to the tank, to see if that helps Fred and The Suckerfish. :pray
