I've had similar experiences with some recent re-houses. M. robustum and M. balfouri are both still sitting on the surface. Don't know why. Both are eating and appear to be fine, so I'm not going to worry about it. I enjoy seeing them.I rehoused my H. Lividum colbalt blue a little more than a week ago and she hasn’t burrowed at all or webbed anything up. Any help?
I did this with some slings when I first got them months ago. I had forgotten all about it. It worked when I did it previously.Wet one side of the enclosure good and start a hole with your finger....tonight in the dark I bet it starts digging.
