A have bought 2 P. metallica and P. "lowland" spiderlings and I housed them in 250ml plastic pots with humid vermiculite. As they have been poor feeders since they arrived, only eating once, one small cricket in 6 days each, I decided to put some wood pieces and a retreat to make them more confortable. I have heard that when slings, they are more fossorial so I placed it horizontaly.. Does anyone can give me other tips to make their acclimatizing more successful? BTW, they are in a undisturbed place and I just check out them twice a day.
