Sea urchins are great cleaners, but can be rather annoying if you have frags in the tank. They tend to take stuff and move them or knock plugs out of rocks constantly.
But if you have no frags or you're not worried about resetting your plugs everyday, sea urchins are an amazing addition to your clean up crew and well worth the money.
