I believe you are referring to the old turtle tank. That seems like a good fit for them too, though I personally like turtles and was kinda hoping we'd get some new ones. Oh wellNo, I was referring to the one on the end "snake wall" near the Lake Victoria exhibit and the exit.
But it could already be in the old flying snake exhibit and I just didn't see it, I didn't spend much time in the ARC today because of a loud school group, and didn't know to be on the lookout for them.
