I have 4 fire belly toads in a 20 long tank. A couple of months ago one of them swelled up, was hiding and not eating. Tried to find info but was at a loss what to do. After several weeks the swelling started to reduce and he resumed eating. For several weeks now he has seemed comepletely normal. The last couple of days he has swelled up again, even larger than before I think. I will try to post pictures of him and the set up but does anyone have any advice to offer?
