well, Alfonso (named by my son ) has made it through the night. He is hiding in a small cup in a plastic box. I have put in some water in a bowl but I don't think it's very interested in having a dip! We have a hermit crab tank so have put the container on the top to keep it warm ? Don't worry, I wont put him in with the crabs.... I am trying to find out how to post a photo so you can help identify it. I believe it to be green tree frog by looking at other photos on the web but will try to find out for sure. We wont release it till we know of we can. We have Brown Striped frogs in our pond so live in a froggy environment! Thanks for your support.
