No I haven't, my mom won't let me. She doesn't view frogs in the same light as cats and dogs so sees it as ridiculous to take one to a vet. How do you dust such tiny insects?? I do have fluker's calcium with vitamin D3 supplement, but even so there's no guarantee I can even get him to eat. So is it possible to force feed such a small frog?
Before my hydrometer broke the humidity always ranged anywhere between 70-80% and nothing has changed since then so I don't know if that gives you a general idea.
