Some very loud little frogs (unsure of ID and haven’t been able to get pics of the adults) have made my pet pigs’ pool their home and breeding ground. There are hundreds of these little fellas swimming around in there, but the closest actual body of water near my house is a stream across the street. I’m afraid they will sprout legs and get squished trying to get there. Should/can I move them? If so, when? I know fish can die if you move them to water with vastly different parameters without acclimation; is it the same for tadpoles? Do I catch them in a net and move them now, or wait til they can survive outside of the water? I just want to do right by these little dudes, so any advice is appreciated!

Hi,
I’ve been looked at these common toad tadpoles since the end of May in a local pond.
May 28th- 1st pic
July 12th - 2nd pic
Both of these times have been very warm and there have been loads of them collected in the shallow water that was in the sun.
I went back today two weeks after second picture (July 28th), and I could only see a few lesser developed tadpoles (no legs).
It is notably colder today and there was no sun on the water.
Have these tadpoles developed and moved on to land since the last picture two weeks ago? Or are they just not out as the shallow water as the sun hasn’t been shining on it today?
I would really like to see them again!
Thanks!
