At my site, we have salt water aquariums, managed by an aquarium company. One day, one of the fish died. And evidently, salt water is home to a shit ton of bacteria, and also it appears that most of the colorful fish are scavengers.
The dead fish's roommates decided to go to town on the soft parts because by the next morning, they had eaten the eyes and a hole through the intestines.
It looked like the Walking Dead had come to the aquarium.
For the next part, you have to know that small children love the fish, especially the clown fish. The overjoyed howl of "Nemo!" let me know when they've spotted a clown fish.
To combine the two, I got to hear a "Nemo!" followed by terrified shriek as they spotted Nemo's necrotic companion.
Best part: shriek was Dad's.
