So I have 2 male fire bellied toads. One is bright green and I can definetly tell he's an oriental. But however the other one is much smaller and is half dark green and half brown. I did some research and found that there are many other species of fire bellied toads but he doesn't really look like any of them. Is it possible that he's a hybrid? Can 2 different species of fire bellied toads mate? If so, which species would he most likely be?
