This sounds pretty neat:
Aquarium workers placed RFID readers on the front of a "Living Fossils" exhibition tank. When the fish move within range of RFID readers, information about the fish pops up on a touch-screen display. Visitors can use the touch-screen computers to find out about each species' name, diet and characteristics
I wonder how hard it would be to implement some sort of tracking with that system? Sometimes aquarium tanks are so big the fish you're looking for is nowhere to be seen.

range and triangulation. Means multiple waterproof receivers throughout the tank to you can stay within range. with the big and open tanks, I think that'd be fairly problematic.
on top of that, I don't think the range for RFID receivers is all that great - and I've no idea what water would do in terms of decreasing that range.
Let's just say there's a reason why submarines use sonar instead of radar.
