I can't help it, here's another one (Brian, this one that came from one of your scorps). It's always been the smallest of the other two and I've always guessed it was an instar behind the others. Right now it's the biggest one. Now a third one is about to molt.. the one on the left and in the last pic. The ones I have thoroughly clear an area before a molt, usually pushing things out of the way with their tail. And it looks to me like they make a very shallow bowl and then turn upside down in it. The one about to molt has a broken telson so, I'm curious to see how that's going to trun out. Should be ok but, you never know.
