he don't eat the wood chip so he will be fine with that but if he starts trying to eat it i will change itI took the plants out and went for a desert type setup, i would advise taking the wood chips out and use a non-particulate substrate such as lino or ceramic floor tiles, i only say that because my BD has just got over a case of impaction from eating sand with the crix.
maybe not intentionally (sp) but if he misses the crix with his tongue and hits a piece of wood chip then he can swallow it and become impacted, or if not impacted it will be very uncomfortable to swallow and pass, but as you said if you noticed it you would change it, or you can feed outside of the viv, whatever suits you best.he don't eat the wood chip so he will be fine with that but if he starts trying to eat it i will change it
