What eats coraline?

[Renelope]

My tank makes coraline algae like you wouldn’t believe, in 8 months all my live rock is covered with thick plated sections growing upward and splotches that are spreading over each other, the back glass and overflow are covered... and I’m having to scrape it off the front/sides every 3-4 days. I’ve got several colors of purple as well as a green variety....

My question is, is there any CUC that eat it? A couple critters to help me keep it at bay sure would be helpful. Thanks!

+1 for the urchins. We had all long spine in our 75 until it cracked. Did a fantastic job taking out algae while we had it.
