From the limited reports of their wild habitats, we have been able to access, the Flat Rock Scorpion Hadogenes troglodytes lives its entire life at the bottom of granite and sandstone hills. These hills are constantly splitting and cracking due to changing weather conditions. Adults and babies are usually found in separate areas on the same hill and do not compete for resources. With this in mind we have a couple of options for enclosure décor and design.
If you’re feeling really adventurous, you can use aquarium silicone to glue the slate pieces to the back of the enclosure with separations between using pieces of wooden doweling. I would give a spacing between the slate pieces of ½” to ¾”. The scorpion will then be able to climb into the spaces easily during the day and then come out at night as it would do in the wild. With the slate being on the back wall, this is a potential maintenance nightmare; you wouldn’t be able to clean the enclosure easily.
