So, I dried him on a paper towel for a few days and coated him with Polycrylic -- which preserved him amazingly well. He is mounted in a little frame that I painted and wrote below him, "Poor, Poor Fishie." He sits on my desk to this day!
The fish below were never living so they would be happy to be mounted on a string and turned into a necklace or some such thing. I think I see more polymer fish in my future...
