I have a 3/4 B. albiceps sling that burrowed - I believe to molt- over 3 weeks ago and I haven't seen it since. I know bigger ts take their own time in such things but is it unusual for a sling that small to stay buried that long? The opening to its burrow has been filled in. The bedding is coco fiber. I keep the bottom layer moist by adding water via pipette down the sides "Tom Moran style." There is always a Lego filled with water. I put a piece of mealworm in just in case but the sling has not made an appearance. Any advice? Thanks
