Thanks for your reply !!
I looked up some frog diseases and the closest thing it could be is dropsy but i dont think thats it. He's not bloated all the way around, its just a round lump petruding out his right side only. It seems to definately be full of air though because its always popping above the water line and it seems hard for him to stay under water. I'm still unsure....
Do you think i should try treating him for bloat/dropsy ??
