The bottom layer consists of a 2cm layer of freshwater aquarium gravel covered by a coco-fiber mat. This will allow the water to drain into the bottom of the tank and be siphoned out if the level gets too high. I put a thin layer of fir bark over the top of the mat, primarily for aesthetics, but also for maintaining humidity. The piece of wood is locally collected grapevine, and the air plants are from my old vivarium. The nesting area is going to be located in between the flat rock and the wall of the tank (right side). I put a small piece of vinyl tubing into the corner that leads to the bottom. I stuffed a paper towel into the bottom of the tube with the rest of the paper towel extending across the base of the nesting area for moisture. I covered the glass next to the nest with a piece of aquarium backing that can be lifted up for viewing.
I haven't settled on the ant species I'm going to keep, so I haven't decided on the nesting material yet. I suppose I will have to keep a carnivorous species since I don't want them to tear up the plants
Any recommendations on good DIY nesting materials? I might collect some sandy soil locally and try to sterilize it the best I can; any advice on this process would be great
. Well, heres the progress so far:
