Rock urchin safe for reef tank?

[reef_doug]

I found a 3" Rock Urchin in my LR. Is he ok to keep for mixed reef (SPS/LPS) tank?

Thanks!

imo it should be ok but i would keep an eye on it with coral, from what i know they are mostly active at night and hid in rock work in the day, so you just got to check up on the coral, i know they will mow down zoos if they are in the way, but nothing they can recover from the a healthy tank
