Soul of the Shell

I thought this shell looked like an eye when I was photographing it earlier!

Thanks for suggestions of names for my pleco yesterday, he keeps hiding & doesn't want his photo taken, but I will take a photo of the whole of him for you one day.
So after comtemplating Einstein, Killer, Gollum, Plec, Peter, Peregrine we have decided to call him Norman! :-D Thank-you Jane!
