Advertisement I thought I'd show a few variations on Lychas enclosures. Lychas are small foraging scorpions that can be kept communally , although as with most, gravid females can be aggressive. The third picture is a 10"x10"x10" cube. It has a false bottom, a wet area with polished stones and sphagnum (this is the only place where water is applied to the surface, the rest of the surface is dry ), and curved bark stacked one piece inside the other and on top of each other to allow for many variations in humidity so the scorpions can choose for themselves. The first picture is a 5"x5"x10" tank , again with a false bottom and a wet corner, but in this case flat bark is stacked upright against the back wall to provide variations in humidity. The second picture is a small enclosure I set up very simply, sphagnum moss kept slightly damp with bark stacked against the back.
