So I got two vittatus this past weekend and I have been keeping them in a tub together just till I know all is well with them. Now twice I have gone into the tub to discover only one of them. But after looking around a bit, I found the other, in the corner of the tub, dug in butt first with only it's head poking out from the leaf litter. Now my tub is about an inch of sphagnum moss and an inch or so of litter. Am I missing something? Is it trying to lay eggs?
