Where are you guys ?!?

I have two species recently added to my collection (two h Gigas and one N vulpinus) since I got them I've only seen them once and I never seen them eat and I got em earlier this week tuesday morning...Am I ever going to see them again? I don't even see them when i go in there randomly in the middle of the night after 12 am but before 6 am....so are they ok? how can i tell if they are in there without risking injury or have them fly out the cage and get lost in the house?

If you can't see them, you probably have them housed correctly. H. gigas are known for digging deep burrows, so you probably won't see them more than once or twice a year, except for maybe the tips of the legs sticking out of the hole. Make sure the substrate is damp, and that they have access to a water dish, and drop a cricket down or near the hole two or three times a week. As long as the crickets keep disappearing, you have nothing to worry about.
