Sexing green tree frogs

[Kurt]

They may eventually feel safe enough that they will keep singing when you look. I know whenh a lot of my frogs start calling for the first time, they have a tendency to shut up if I moved to look at them. But after a while they become bolder and won't care if you're looking. When my red-eyes went into the breeding chamber for the first time, they wouldn't shut up, even if I put my hand there with them. My male tomato frog started singing while I was feeding the tomatoes. My fire-bellied toads will even call if they are in my hand.
So just give them time to get to know you and realize you are not a threat.

its funny, 5 minutes after i posted this on the forum one of them started to call and i happen to be right by the terrarium and saw it. now im just wondering if the other is a female.

These are pretty easy to sex - hold the frog behind the forearms and lift up its head - check the throat area for (a) dark colouration and (b) if it has a vocal sac.

sweet than it appears i have a male and a female. without even trying.

@ JC,
So if they do have the vocal sac & dark colorations, are they male or female?

Also, I just added another gtf today, it is already made itself @ home in the enclosure... lol

[John]

Vocal sack means male.

Yea, I kind of figured that.. lol *thumbs up*
What about grey's are they the same??
I have 2 gtf (female) & grey=male if the above is the same.
