This I found very interesting:
The first time I put crickets in the plan, the frog saw them and jumped in. The second time, I had to coax him in, but once he was in, it didn't take long for him to grab his lunch. But ever since then, when I go down to my "basement greenhouse" in the morning to feed him, he's sitting in the pan, waiting for breakfast. After he's had his fill, he jumps out and spends the rest of the day resting on a leaf.
I keep saying "he" but it may very well be a "she." I suspect it's young because it's still green -- the guy at the cricket store said they are gray when mature. No singing at all, but it may be the wrong season -- though to the frog, it must feel like summer because of the warmth and light duration.
