Just like in Cane toads. I noticed when I got my male Bully then I got another which was supposed to be male but turned out to be a female.
I questioned the seller because the frogs bottom was rounded.
The baby has to be a healthy weight in order to tell properly though, if it is under weight the bones stick out on both sexes.
Actually you cannot go by the tail bone. All the protrusion of the tailbone means is that the tail only absorbed so far. I've seen protruding tailbones on several species of frog and it is in no way an accurate way to sex them especially not in a Pyxi. All that determines is that the tail didn't absorb as far as anothers did. It is a good way to guess. Tried that with Ceratophrys and the tailbone has nothing to do with sexing.

Its much too young to sex and it keeps going through changes rapidly. The head alone compared to the body is huge, but then again its still basically a baby. The growth rate so far is ridiculous growing from the size of a quarter to 3.5" in less than a 3 weeks. Which is a males growth rate. I do have a knack for getting fast growth rates from my frogs though. My male C. joazeirensis reached 3.5" in exactly 1 month which is insane. Its all in the diet.

In the end as of now we cannot determine sex accuratly. Its a waiting game. In all honesty though I bought it just because its a GABF not hoping for either sex in particular. We shall see.
