|Polychaete on barnacles|
I moved all my animals into a larger tank two weeks ago, transferring the sand, the planted eelgrass, the stones and shells, then the hermits and crabs once everything was going again. While I was combing the sand with my fingers to make sure I got out all the scrambling critters before the serious earth-moving started, I came up with a 3-inch polychaete. I don't know who was more startled, and I dropped it and/or it slithered out of my hand instantly.
The only worms I have brought into the aquarium have been microscopic. I've been watching them grow and make their tunnels, skinny red wires reaching up to the sand surface. I'd seen no sign of one of these big (and they do get big!) paddle-footed predators. It must have grown up in the tank in the few months it's been operational, since the beginning of September.
(The one in the photo is from 2010; I didn't chase the newcomer down. I'll let it grow for a bit.)
And something small, that will grow, soon enough:

By the dotted antennae, I gather he's a hairy hermit. He's too small to see if he has blue knees.
Tomorrow, weather permitting, the beach!
