Strangest thing you ever found in your tank?

When I was first placing the rock in my tank.... a little creature fell out of the rock and wiggled around on the top of my acrylic tank then fell inside the tank to disappear.

Later...like a year or two I learned from the cracking sounds that it was a Mantis Shrimp!
He's in Mantis Heaven now

My cat, she fell into my 90, fraged a bunch of corals and climbed back out.

My Hands,
I used to find them in there all the time until I learned that hands are one of the worse things you can put in your tank.
