I am new to the fire bellied toads I have two concerns. I had someone give me a 4 year old fire bellied toad and when I brought it home I read and I have educated myself A lot from reading things on the internet .. So I read they do better in groups of two or more so I went to petco and bought two new, younger ones but they are the same size of the fire bellied toad that's 4 years old that was given to me . He/She is a dark olive color and has been ??? and I also noticed it started to get "fat" ...
