Advertisement I recently changed the substrate in my E. pachypus enclosure. It has been several hours since I re-housed her (since about 2-2:30 pm) and she has not yet burrowed. This is strange because when I first got her she made a burrow in hardly any time at all. I did use a different sphagnum substrate, though. My exotic shop has a shortage of the substrate I used to buy from them, so I've since been using Schultz from Wal-Mart (100% natural organic matter). Could she perhaps have a harder time burrowing into this new shagnum for is she still just getting used to the new surroundings? Even at this hour she seems to show no desire to burrow.
