Hi my Dad LOVES salt water fish we have lots of fish and coral! He used to be the president of the marine life aquarium society of michigan about two years ago! He is not the president any more but is still verry involved! He is the newsletter person! Any way I asked him if he ever heard of a banded shark and he said no but he has heard of a bamboo shark he said the only other kind he has heard of pepole keeping is a nurse shark! You can e-mail him at [email protected] or if you get this in the next week oyu may want to e-mail me at [email protected]. His office is in the basement he just had surgery today so I doubt he will be going down there for a while! Hope to help
