a lot of people say u shouldnt even try feeding them for at least a week or 2..but then try a feeding stick and put a pice of silverside or other meaty food on the end and put it right in his face..my 3 week old bamboo doesnt really hunt down food it waits till it swims over it or i put it right in his face..but the lfs said they started my shark off on ghost shrimp..and i feed mine that every once in a while too..so try to put the food right in front of it..but again maybe wait a week or so
