I too agree with buying a few (froglets) & raising them until you can confirm the sex. This is actually what I did. What I really wanted was 1 male & 1 female. So I bought 4 froglets. Some mos later, I realized I had 3 males & 1 female. Guess I hit the jackpot lol. I had originally planned on keeping just 1 m & 1 f. But now I dont know if I can part with any of them lol.

If you can swing getting a few of them, go for it. You probably already know...but keep in mind, they eat A LOT. You may want to think about breeding their food to be more cost effective. Dubia, crickets etc.

Btw, I bought mine from UndergroundReptiles. Ordered them through phone. Great experience. Good price, good s&h, & nice, healthy frogs. I would do business with them again without hesitation.

Good luck getting your male!
