so the other day i was looking at my urchin and noticed that what i thought was its mouth had legs and after looking closer i found out it was a crab but i dont know waht kind and if he is harmful to my urchin or my tank. the picture is kind of bad but he's brown and off white stripes with a flat shell that is jagged towards the front of it.

NEAT! I saw this on Discovery. Likely you have a good little crab that protects the urchin from predators. The show showed the crab attacking would be attackers.

Thats so neat!

thats what i would say as well. its like having an anemone shrimp (ghost shrimp). you got yourself a cool little guy there
 
wel thats good to know he is pretty awesome even though i know here there he is still hard to find he blends in so wel with the sea urchin. does anyone know the name of the crab just so i know?
