Look at the carnage
See Inside Your Fish Tank : GizmodoReverse periscope lets you look at fish while they eat. "Use slow gentle movements so you don’t create turbulence in the water and disturb or frighten your fish."
I think it would be more fun to attach some sort of bluetooth camera to a fish (does bluetooth work under water?), then project the moving image all over a wall.
