Ok got a piece of Rock yesterday, small piece with lots of things growing on it. The hermits did a **** of a job cleaning it up. Then tonight the light comes on (timer was set wrong) and this scary looking little worm/critter was crawling on an old piece of rock. Pics not the best but it is pretty small, less than 1/2 inch. but evil scarry looking.



thanks this hobby rocks !!!!!!!!!!!!!!!!!!!!!!!!!!

thanks I was thinking that but never saw one up close, but this came from a rock in the waters off South Florida and I did not see much mention of them here. After more research I see they have been found off Boca Raton, which is right down the road.

Thanks again for the answer.
