Keith Posted December 9, 2012 Share Posted December 9, 2012 I used to keep dubia in egg crates long ago, but even with a good diet they never thrived. I switched to repti bark as substrate and have real wood decor in the tank along with giving rotting tree bark and old leaves. I notice after the roaches eat food they ingest bark, it happens daily and I always see a small dark area underneath the abdomen, I assume bacteria to digest the wood. Anyway, my roaches are healthy and thriving so I would say wood/bark is essential if you want healthy stock. Quote Link to comment Share on other sites More sharing options...
