I got these guys a while ago (March), and as young, they spend considerable time underground. I was reluctant to dig for them for fear of injuring them, but I only ever saw 3 topside at a time, and was beginning to wonder if one had perished. Apparently not - Yesterday, four were topside, and one is getting much bigger much faster than the other 3 (The 3 I kept seeing were roughly the same size. These guys were all the same size when I started.) Here are "Then and Now" pics!
