Hello Please Help!

Hello I have 2 Fire belly toads.
I went to feed them today and noticed my older one (male) kind of floating in the shallows.
I tried to take him out he flipped on his back and just floated there I got him out wrapped him in a towel and now he is in warm water (just a bit) with a dash of honey.
He is defintely sick and just is kind of lying on his stomach.
I have pictures. I also notice he looks chubbier than yesterday and has a bit of fluff like when a goldfish dies.
