When you buy a piece of live rock, you never quite know what sort of tiny creatures have made their homes (or nests) on it, so it's really fun to keep watching as things change and grow.

If I had to name him, it would be Elephant Snail because of his weird trunk. Very strange. He could be in a Dr. Seuss book, I think.
Lots of other things are growing too, like our corals and this huge anemone (2nd picture):
