Urchin on Foam rock walls?

[Tahoe Reefer]

Does anyone have experience with urchins in tank with foam rock work? I'm concerened with the urchins scraping away at the epoxy coating over th foam.

Anything with a mouth will scrape the surface clean. They will not eat it directly however.

They will destroy it, trust me.


I tried it in my foam wall tank and the urchin removed large pieces of foam.

Thanks for the input. I think I'll just stick with snails,
