We have a pretty large viv and it needs an extra something. I'd love to have some kind of greenery in there that is not harmless to Beardie but am really not sure which we can use... I heard somewhere that you can use succulent cacti and then he can eat them but I'd rather have confirmation of that!
Please make sure you take the humidity levels inside your tank into consideration before adding them. Most people find that adding real plants throw their humidity levels way too high risking Respitory Infections for your beardy.
