Hey man, thanks for sharing, sounds like a great gig!
I'm a volunteer diver at the Dallas Aquarium at Fair Park, Dallas, Texas
( the city's aquarium). Unfortunately they don't let us dive with the sharks, the tank is only about 5' deep by 6-8' front to back by about 20-25' long, I keep trying to talk them into letting me give it a whirl, but they're not buying it yet. Maybe if we get our expansion ever done we'll have a tank big enough for us to dive with the sharks.
We do our diving in the 'Flooded Amazon Rainforest' exibit, a 12,000 gal. tank with about 2000 total fish including 2-3' armored catfish and 3-40lb. Pacu, ( a fish related to piranah, but vegetarians). We do feeding and maintenance dives also.
Just curious, why clean up the leftovers, the fish should do that. Is it to help keep the tank clean or a way of monitoring what the fish are eating? If we have any uneaten scraps we just leave them in the tank, the fish will get to it.
when the aq is open to the public do you guys put on any type of 'show'? we go in with a full faced mask that has a mic in it and headphones so we can talk to the guests and answer any questions they might have.
