Yeah at first I kept mine with basic coco fiber, but I did have small cork pieces for them to climb. When I upgraded though I mixed in some cypress mulch and leaf litter for them. Not necessary but they will make use of it. Now I have large vertical/diagonal pieces for them. They will need more room as adults it seems, and more climbing space provides them with more surface area. I keep mine fairly high humidity and warm, but they seem to be able to tolerate drier conditions to an extent. I think the Eublaberus would outcompete the giganteus eventually and stress them more. Eublaberus are too prolific and eat anything haha! Love feeding the genus!
