I am attempting to create a small outworld for my Crematogaster for when my queen get her first nanitics. I was thinking of filling the bottom in with a layer of this clay, then sprinkling some substrate on top. Is air dry clay okay? Or will it kill them? Thanks in advance.
Also, what drill bit size would I use for a 13mm OD test tube?
