Hi i had the 30cmx30cmx30cm exo terra spare when i was first looking at pac man frogs and are using it currently for my frog i know the 10gallon tanks like what you get in the zoomed amphibian/pacman kit are what most care sheets state to use when their bigger,at what size would you say this exo terra is too small?? heres a picture of its size now.

When you see it's obviuosly too small for a frog.
FYI most males cranwelli are perfectly contained in your sized tank all their life
so you gotta go with a gut feeling on that
