I use self-cleaning aquariums for a lot of my smaller scorpions,they are about 10" high,and 4" square at the base,flaring out towards the top. I set them up with a false bottom.
After observing that my Isometroides vescus (spider hunting scorpion) spent time each day on a polished stone as part of it's daily routine,and that the stone always had droplets of condensation on it,at least around the base where it first protrudes from the substrate,I thought I would use this natural behaviour to my advantage.
In setting up subsequent enclosures I set polished stones into columns of peat in the substrate,running from the false bottom to the surface with the top of the stone protruding.
Usually I check and feed my scorps on Wednesdays and on the weekend,today is Saturday,and due to ill health I haven't checked my scorps since last weekend,the substrate in some is quite dry. Today is quite warm,34 C,I look today and all of the Lychas spp. and some of the Urodacus spp. kept in those tanks are sitting on,or next to the polished stones,body pressed to the peat,the stones actually look wet,most times droplets can only be seen around the base with magnification. Obviously the peat is 'pulling' moisture up from the false bottom and condensation is forming on the stones,the ambient temperature in my 'scorpion corner' is 29 C.
To me,this seems like a good alternative to using a tiny water dish (bottle cap?) in a small enclosure,and totally natural behaviour for the scorp.
What do you think?
