hey , heres what i did when i first got my banded bamboo shark, i started offering him live food like ghost shrimp he started eating those up right away, so i recomend doing that, but im gunna warn you, brownbanded bamboo sharks sometimes wont eat for awhile after being hatched,so if he doesnt eat in a couple of weeks, try force feeding him, if you dont kno how then go to a vet. and they will tell you or do it for you,but that usually you shouldnt have that problem so dont worry, but if you do have to force feed him after that then they start eating on ther own, but i strongly recomend geting a book called "sharks and rays" by. scott w.micheal that book will tell you every thing you need to know about housing a shark.
