Can anyone tell me about them.Just curious!We saw a couple good sized ones at a LFS and they seemed to move their little stickers around alot.Just wondering what everyone had to say about them.Not likely to get one just curious.
have a pencil urchin, and he goes all over my tank. I periodically feed him a piece of krill or squid with my feeder stick. I just hold it in a couple of his spines, and he closes down on it and eventually moves it to his mouth to eat.
