Actually, if you want to keep a shark, you need a fine sand substrate, and minimal live rock in the tank, believe it or not, sharks have sensitive skin and bamboos spend most of their time on the bottom. It would be a good idea to use a DSB and put the LR in a sump with a good light on it, reverse photoperiod would be ideal. I know that there a few well experienced shark keepers here that can give great advice. I would start a new thread with bamboo shark in the title, you'll get their attention. HTH
