I keep my hissing roaches in a 6x2x2 feet terrarium, and 3 have died . The decor is Spanish moss, sheet moss and sphagnum moss. As for wood, I use cork bark and oak wood and oak leaves.the substrate is eco earth, sand from Home Depot and coconut husk. I feed them fruits and veggies and the box has a mesh lid, but I water them every day.
