Not a popular opinion, but I don't like the look of coralline. In fact, I like the look of brand new dry/dead rock (like marco rocks). In a past tank, I had a tuxedo urchin and my tank's surfaces always looked brand new (not sure if it was a coincidence, or that my tank was so dead coralline and other algae never were introduced).
Are there any reef safe urchins that are known to clean a tank of coralline?
