I have a few emeralds in my tank that I don't see very often. Usually just a claw sticking out of a crevice every now and then.
The other day I had a shed or dead moment when I saw a fairly large one sitting stationary on a piece of rockwork all day long. It wasn't in a place that was easy to access, so I figured it would take care of itself either way. There were shell parts in the area the next morning. Today I saw this monster peeking out of a hole nearby. For scale, that little cave is about 2.5" high. I'm not sure how big these guys get, but it's a monster compared to the others I have.
