Hello Frog community,

Santa brought my 9 year-old frog lover daughter two juvenile white's tree frogs this Christmas. As expected, I (mom) am doing all the researching and feeding and caring, but quite unexpectedly, I have fallen madly in love with them! "Pickles" has doubled in size since we got him 18 days ago, but "Pepper" has remained pretty much the same. She's not a very effective hunter (one cricket actually hid under her while evading Pickles) and seems content to eat one cricket while Pickles leaps across the tank picking off the rest one by one. I tried feeding Pepper separately - first removing her from the tank to feed and then removing Pickles from the tank while she had full reign - but nothing changed. She doesn't appear to be impacted (watched her poop the other day) Could they possible be that different in nature or should I be trying to locate an exotic pet veterinarian?

P.S. I say "he" and "she" without knowing for sure. How can I tell?
