well from that thread , i gather you used a plastic cage. that has a flip lid , and a plastic window on the lid. these often used for hamster transport or like what you said, hermit crabs. i have one of these. is the idea to weigh it down with smoething so its stationary, and keep the lil guy in "male jail" , letting him out under your own supervision every day until he isnt chased away after 5 - 10 minute testing periods ?
if so, how do i get the little guy back into the jail ? i can just see him running off into the rock work now.
