Sea Urchins and SPS

[manix man]

Is it safe keeping sea urchins with SPS corals. The ones in the tank are a long spine and 2 rock boring types.

Only reason I ask is there is a bite size taken out of red plating monti in the tank. It's the second time it's happened and was wondering what to narrow it down to. The red plating is actually growing far faster than the damage caused so not critical yet. It seems the only sps effected in the tank so far.

They are not very safe IMO. I had one that ate a line right across a Monti cap frag I have.

I think I will have to keep an eye on this. Like you say you had a problem with a monti cap which is sounding a bit like what I am having. Branching acros and montis don't seem to be an issue.
