Avoid The Green Ones

"Don't eat the green ones, Kent; you wouldn't like the Green ones"    

 - misquoted from "A Fish Called Wanda"

I watched Total Recall (the Schwarzenegger one) and at 1:31 in the playback, the master villain kicks over his fishtank in a fit of pique; cut to a closeup of poor dying goldfish, gasping out their last, symbolic (I assume) of the martian workers he is starving of air.
     What follows is a woefully incomplete list of media containing GFV (gratuitious fish violence)

A Fish Called Wanda

Finding Nemo (yes)

the Deadliest Catch

The Life Aquatic

20,000 Leagues Under the Sea
