Ok. I'm usually pretty good with not worrying about my spiderlings but my new cobalt blue just has me puzzled. He's made his burrow in 2" of substrate but as far as I can tell he hasn't moved one millimeter since finishing. Not even chased down a pinhead cricket. Bout five days now which is the longest most of my spiderlings will go without accepting a meal. I know adults are pet holes but are the baby's as well?
