I'd like to hear from folks who's T's have done major excavation and enlarging of their burrows. I watched my 3" juvenile A. geniculata doing mountain building today using soil from its burrow. Then I looked at my little B. hamorii sling doing the same thing in its deli cup. It has been very hot here (as in many places around the country), and I'm wondering if the behavior is heat-related to try to create a cooler borrow by digging deeper. Or, since they've been eating more in the hot weather, are they enlarging their burrows in anticipation of needing more room to molt down there. What has your experience been with this behavior?
