sorry noone awnsered, how long is he? while their small they need more food and nurishment to grow, i would suggest a minimum of 4 times a week, if you dont feed them enought they will slowly starve to death. its happend to me twice allready, i just gave up on bamboo's and moved on to blacktips lol very easy to feed they eat about anything you put in the tank with them(includeing hands) but you also need to vitiman enrich his food and feed him a varied diet for long term sucess. best of luck and if you have anymore questions ask, ill keep looking at this thread and get my fellow shark enthuiast Krj in the conversation.
