He will constantly forage and dig. He also will dig out a hole to sleep in. You need to be sure all the rock is secure. but any minor concern of rock slides outwieghs his ability to maintain your SB.

so the clean sand is worth having him

He is hands down the best SB CUC you can get. Mine never stops sifting , put trash , dead coral , shells all in one area.
Your Sb if properly turned and cleaned and the flow in the tank is up to par then the SB will convert nitrate into harmless nitrogen. But if dirty and never turned just causes nitrate problems.
