I have 2 Canyon Tree frogs. They are pretty close to the same age as each other. One is about 2.5" but the other is about 1.5". A few weeks ago, the smaller frog had a hard time passing a cricket but after a few days it did passed. Since then I have seen fresh poop by her so I'm sure she's eating and isn't blocked but her body is getting very skinny. Currently I can see the bones in her lower back. She is still active at night and if I disturb the leaves that she's hiding in, she doesn't have any problems hopping away but I'm afraid she's not going to live much longer if she doesn't start putting some weight back on.
Any ideas on what might be causing the weightloss or how to help her would be greatly appreciated.
