I feel like you do. No one seems to post much here anymore. I wish that I could help you with your question of the frog swimming upside down. I have one of my own that's looking like he can't stay on the bottom. Keeps floating back to the surface like a magnet is pulling on him. Seems to keep struggling to go to the bottom to rest, and he can't do it. I'm sure that this is stressing him. There used to be a website that you could see pictures of tadpoles and ID them. I'll see if I can find it for you. If you indeed have a leopard frog, then care is relatively easy once he morphs. Half water/half land would do or even a nice size soaking bowl for him with a slighty dampened substrate. I'd make sure he has as large of a container as possible as this one moves about quite a bit. Has to stretch his flippers, you know.
