No.

Wiggles92;3181847; said:It wouldn't have to be a completely sealed tank, but yes, a completely separate one would make more sense; I just thought the option of making a sort of dual level cage might be a compromise to the original question. The mudskipper would still have to go, though. Dart frogs usually get fed foods such as flightless fruit flies and pinhead crickets, both of which shouldn't bother the turtle. I do know what a turtle needs and I have read multiple articles on dart frogs care in REPTILES magazine; I haven't a clue on the mudskipper which is why I omitted it from the OP's design. This design is completely hypothetical, of course, but it should allow for both animal's needs to be met.
Wiggles92;3182062; said:The turtle would be fine at that high of a humidity but airflow is still needed; the basking spot is where you could run into trouble (depending on the size of the enclosure) due to the possibility of overheating the dart frogs.
I have done some research outside of reading care articles, but probably not as much as I could have; I do realize that dart frogs can be quite delicate, so I think I'm going to have to agree with you that this would not work since you have hands-on experience with them. My intention was to present a possibly viable alternative to a flat out "no" to the question; I apologize for presenting an idea that could have proven fatal to one or more of the animals mentioned.
Maybe tree frogs such as green tree frogs would be a better idea for tankmates for the turtle since they live in the same area?
