I've not kept them. I have kept tuxedos and currently pincushion urchins with no issue.

Seems like the consensus is they have been known to eat coral.

In 55 years of reefing, I have never seen urchins of any species eat coral.

They do eat coralline algae.

They will not harm coral on purpose but may accidentally knock stuff over. Got one in my tank right now, maybe 4 inches. Had one about 8-10 inches, I got rid of him because he kept knocking things over.

The OP on that thread questioned the scenario that a starving urchin would eat coral. I suspect that may be the case. I keep ornamental macro algae in my display tanks, so urchins are well feed.

I missed that part and of course they would to survive. Similar to the coral eating peppermint shrimp that I keep in many tanks but I feed them. Thanks for pointing that out.
