sorry, but 8 months and the bamboo is only half a foot long? that's newly hatched pup size. at eight months it should be at least 18 inches. tank sizes for sharks is grossly underquoted, maybe you've read "aquarium sharks and rays" by one scott W michael? take his tank sizes and multiply by 200%, and that's just for benthic species. you guys think it okay to keep a 4' long shark that DOES swim around, be it occasionally, in a tank that is half it's length? i'm sorry, but elasmobranchs being my main focus in the hobby, i can't sit idly by and see you mistreat this animal. it's unconscientious or miseducated hobbyists not unlike you that make it difficult for others to responsibly keep sharks.
who? conscientious hobbyists, that's who.
the brownbanded bamboo shark is a tropical species.
i'm honestly sorry if i was too harsh before, but as i stated, sharks are a touchy subject with me, because i see all to many people trying to keep a "banded cat" in a 55gal or a blacktip in a 180gal.
to anyone interested in elasmobranchs, i recommend visiting www.monsterfishkeepers.com, they have the best shark and ray forum, after www.sharkraycentral.com
i am also a regular poster on monsterfishkeepers, the saltwater section could do with some of you guy's input.
many of these guys are professional dealers and public aquarists, and are the ones who you should take advice from, not random sites.
i just hope the animal can lead a healthy and comfortable captive life.
