I bought a pair of phyllomedusa sauvagii's from LLL Reptile September 1, 2011. I reckon they were roughly 1 month old but not for certain.One of them was smaller to begin with by a tiny bit... They are both eating very well are both look very healthy.. Just the one frog that was a little bit bigger to begin with is now twice the size of the other one.. I dont understand. does that mean 1 is male and the other is female or does one have some kinda growth problem.. Please help me with some sorta idea of what is gone on....
