Man, I have to chime in hear on the side of not keeping a banded shark in a 130. WAY too small a tank for a creature like that. IMHO, sharks (all species) should belong on the list of restricted species for a responsible aquarist, along with gonipora, moorish idols, blue spot stingrays, etc. etc.
One other thing, I'd be careful taking a lot of advise from a guy who is keeping "lion fish,Blue spot stingray, a couple of triggers and a miniautus Grouper" AND a 2+ foot shark AND a 2+ foot eel, in a 200gal tank?!?!?!? geesh, why not save some money and stuff them in to a shoe box?
If this gets interpreted as a flame, well then, so be it. It's not personal, just my opinion. As Dennis Miller says, "That's just my opinion, I could be wrong"
