I got 100 adult and 100 subadult red runners delivered on Saturday, and moved them into the setup I had ready. It's an opaque 40 gal rubbermaid tub, heated with a 25W heat cable, and large holes cut in the lid covered with cheesecloth. inside I put a cardboard structure I built with several diagonal panels to provide lots of surfaces to hide on. There are ~.25 in air holes all over the exterior of the hide.
I originally gave the roaches slices of carrot, water crystals, and a dry powder mix I made using a recipe from GeckoForum (whole wheat flour, soy flour, brewers yeast mostly). They didn't seem to touch the carrots, but I can't tell if they went after the dry mix and water. Yesterday I gave them some orange to see what they would do with it.
I've been finding a few dead and near-dead, but I'm guessing these are from the stressed of shipping.
Any advice?
