These urchins eat coraline algae?
Yes. I've seen reports that some won't through well established coralline but I frequently drop one of my mine in my sump to clean it up. Usually takes a few days.
They are IMHO amazing CUC otherwise as long as you glue your frag's down. My favorite algae destroyer.
