Well, what we'd do for a Halloween party would be to make a Toxic Aquarium. Mix orange and blue jello to get a putrid shade of green.
Lifesavers make old tires and you can toss in other junky things for trash on the bottom of the sea. Something barrel-shaped (root beer barrels?) for that illegally dumped toxic waste. Float your fish upside-down on top, and add a plastic skeleton or two. Haven't figured out a good way to put something on the bottom to represent the sand.
