I am new here, found this site while trying to find info on Gray tree frogs. We had about 500 tadpoles in our pool this spring. We moved them all out into a smaller plastic pool and kept about 10 in an aquarium inside. Turns out they are Gray tree frogs. I have a few questions though. The ones outside the water is really green, should I be trying to change it? It is all rain water, no tap water, and I really don't know how to clean it. I am worried that it will kill the tadpoles. A few have little front legs but most do not. We are feeding them frozen kale leaves plus they are eating leaves and berries that have fallen. Is that enough? Why are they so far behind the ones inside. The ones inside all have back legs, 4 have front legs and have lost their tails. They are in another aquarium now. We planned on releasing them but they seem so small and defenseless so should I wait? If so what should I feed them? If they can be released where should I put them, near a pond? I really appreciate any help. I really did not want these guys to die in the chlorine water but we are not very well equipped to deal with so many of them. Thanks in advance!
