I just replaced my two hides with larger ones. He got to the point that it would be more him curling up and his hide resting on top of him than him fitting inside! The new hides are actually way larger than they probably should be, with lots of extra room, but I couldn't find a middle ground so I am hoping he grows into them. I know they prefer cramped hides, I would have grabbed smaller ones if I could have found some, but good BP hides aren't so common!

As an aside I also bought him a whole new Exo Terra tank - the 36 X 18 X 18 one - because the new hides didn't fit in his old 20 gallon tank!

I just figure now I won't ever have to upgrade anything again.
