Living in my rockwork is some kind of critter with half-a-dozen arms/legs. These arms are very thin, (about the thickness of string), and can stretch to two feet long. The arms are banded red and white like a barber pole and are constantly poking about the rock and sand. I'm thinking Spaghetti Worm but can anybody confirm this? Sorry, I've tried but can't get a clear close-up.
