I would stay away from CC with aggressive tanks . just because the fish are messy and food gets trapped in CC.
Banded cats / bamboo sharks are kinda touch and go . I would hold off untill you have a little more experiance. perameters can be good and you'll still have the shark pup die. they are very touchy. any stray current in the tank will kill them. they can go on a hunger strike and not eat thus killing them . If you really must get a shark its best to wait for your tank to be well established at least six months of good perameters. if not longer.
I belive the name of the book is Scott michaels aqurium sharks and rays (if I'm wrong please corect me ). Pick this up before getting a shark this is a good place to start .
