Croaking info

[Odica]

A few days ago I was looking at green frog calls on YouTube and my frogs started croaking. I thought it was the coolest thing. Now one of them is doing on his own alot. He did it 3 times of croaking in the last hour is it normal for him to croak and the other not call back at all?

It's possible you have a pair, females don't usually call like males do

Ooo ok. Is there a way other than croaking to find out if it is male or female?

The males have darker skin on the throat and a vocal sac (the area that looks like a bubble when he calls). Females have a more rounded body shape and no vocal sac
