Yep, I agree on removing what your PAC doesn't eat. They do bite the frogs. In my large retf viv I had a few I couldn't catch and there are now tiny baby crickets in there that are not fun to remove.

Pacs don't generally pass feces everyday. Every few days is fine. Mine go about every 3 to 4 days. If there bellies bloat up after that and still no poo it's time for a bath, haha! They usually go fine though. A nice soft worm dinner usually helps .
