I don't see it being too good for the fish either. Everyone will be trying to get their attention and make them come to the handling holes, and then why would you want your fish handled anyway especially by an uncontrolled public. It's a neat science trick but its being used a foolish gimmick in my opinion...again I'd fill it with poisonous jellyfish.
is that a TRIGGER?? those fish could bite the hell outa anyone that sticks there hand to close to it... believe me i was attacked by one while spear fishing ( cant say it wasnt unprovoked!!)
