Male or Female?

[falconez]

How old is he/she?SVL lenght?Wich is his/her attitude (aggressive,voracious eater & constantly hungry)...and,more than all,did you notice if he started croaking? In that case you would go straight to male.
Looking at the 2nd pic I would go for male due to head shape,but this is not enough...difficult to tell if the dorsal stripe is still visible (and,again,this wouldn't be enough).
So...let's know someth. more about him/her (see at the start of my post) and then we will able to tell something more...

Heading for female.

With it's size and not hearing it croak then I would go with female too. A better picture of just the side of the frog and a better frontal view would better help determine its sex.

I'm leaning towards female, too. And I honestly don't think aggressiveness is a sure sign of being male. My female is extremely aggressive compared to my male, yet half his size. Though my male packs away 3x as much food as she does.
