So last weekend I took some gray tree frog tadpoles out of my pool. At that time, they didn't have any legs (not even in their tails). By Thursday, they all had full-grown legs. But the tadpoles in the pool still don't have any legs in their tails at all. And What is stranger still, this morning, none of my tadpoles had arms. But when I came home, one of them had spontaneously grown full grown arms!!! And when I fished him out, he jumped off of my scooper. I freaked out and put it in another tank with some soaked paper towels at the bottom. But...none of my other tadpoles have arms at all!!! Any explanations? And should I keep the one with arms in the new aquarium without feeding him until he absorbs his tail? Thank you.
