One of my beardies has the same toe issue. He also has a clubbed tail - I think from retained shed. I got him a few months ago, and he's happy now at least. He's a citrus yellow/citrus orange mix. Very pretty.

As for your froggie, I would use the treated water with a little bit of Pedialyte mixed in, just to make sure he's hydrated. Make sure you get the unflavored stuff. I imagine once you get him up to the proper temps (and fully hydrated) he'll be an eating machine.
