No, Fire belly toads have some toxins in them that may not be good for other frogs.
Fire belly newts both should get along unless there both females. They will stay away from each other but if you put a female and male together you will get a surprise also i think the blue belly newt will get along with the fire belly cause my friend haves both blue belly and fire belly and they get along just fine!
fire belly toad is not eating his food
Fire belly newts are smaller than a marble when they are born.
usually green sometimes brown but they are also based on fire earth wind and water so blue, red, brown, purplish brown
