Trying to find a cannon fish tank ornament

There is a big cannon to the front of the armoury,but you're going to need a big tank.

Cannons don't work under water

Thanks Ramboue, but I had seen that one and not sure if it will rust or contaminate the water. Might risk it but would prefer one made for fish tanks if possible, and Id prefer not a sunken ruin one.
