I agree with this. In 12 years in the hobby I have never had to dig up a sling and I would assume most experienced hobbyists would agree. Your setup looks good, slings require a little more moisture than juveniles and adults because they don’t haven’t developed a waxy layer on their exoskeleton that retains moisture. I keep at least part of the substrate moist in all of my sling enclosures. IMO the fact that it settled in and burrowed means that it feels comfortable. I agree with [USER=4947]@Nunua[/USER] that patience is a big part of this hobby and I can’t wait to see your collection grow!
