Urchin Problem

[disaster]

Will urchins feed on anything else except my corraline algea. If I want the corraline to continue to grow should I remove the urchins
Thanks

I had an urchin for 2 days once. I could follow where he went on my rock by the trail of white rock that I saw. I returned him. Too bad too because he used to carry around a rock on top just like a hat.
