If you're talking about a tuxedo urchin, they will eat green algae before munching on your coralline. But if you just want one for diatom algae, stick to snails. They like to decorate themselves with whatever is loose in your tank. So if you have a lot of loose frags, not a good idea. ;]

urchins will stick to your rock work most of the time. they dont do enough to the algea on your glass. this is were you either need o manualy remove it or buy some snails to help out with it.
