They arrived Wednesday and I set them up in their little 16oz. deli cups. Each cup has a little rock, a plastic plant, and a water bottle cap for drinking. Substrate is straight coco coir. I tapped the vials for the first few and got them out, but then I decided to just leave them in their vials and let them come out on their own. I figured they'd come out at night. Most of Thursday, I was busy and just left them alone. I figured I'd check on them and try to feed them this morning. All of the ones I left in their vials were still in their vials. Seems they like their vials better than the enclosures I made up for them: Eventually I got them all out and in their enclosures, and then I dropped a little Blatta lateralis pinhead into each enclosure. I had lots of time this morning, so I sat and watched each spiderling for a little while to see how they would do. The first four had spent the last two days in their enclosures without their vials, so I figured they'd be comfortable and hungry. Nope. They all ran from the roaches. Number 5 was the only one that ate, and he/she was one of the ones I had to dump out of the vials: None of the others took their roach despite the roaches running right in front of their faces. Hopefully, they will feel a little more emboldened by the night, and take care of business in the dark.
