What type of Urchin is this?

[150 Gallon Reef]

I found this urchin on a piece of Liverock I just put into a tub to cycle. I think this is a short spine urchin but not 100 percent sure. Is this reef safe? I have a tuxedo in my tank now, will it be an issue with the two together?

Where did you get the rock? Could be short spine or rock boreing if it's Caribbean

Most urchins aren't super reef safe. I can tell you it shouldn't be a problem with the tuxedo, as long as they have enough food together.

It was from a previous tank setup.

When you say aren't super reef safe, what do you mean by that?

It depends on the urchin. Some will directly eat coral, and a lot will just bump into coral and accidentally chew on it a bit. Tuxedos are the least likely to bother anything.

This urchin looks to be a rock-boring urchin of some species, since it's got that perfect cavity it sits in. As far as I know, they tend to not eat coral intentionally, but may run into it and scrape at the edges sometimes while trying to eat algae.

Did the previous tank have coral? If so, whether that coral got eaten should tell you if this is reef-safe.

I dont believe the tank previously had coral

Agreed likely rock boring or short spine black....
As far as Urchins OP, currently have had 3 over about the last 10 years. Pincushion, Short Spine Black and Pencil. All model citizen's over that period except the Pencil went rogue and started getting a taste for softies out of the blue last year. Back to LFS for it. Just keep a trained eye on it for now. This little beast may do some exemplary work for you down the road....no issue the two together imo.
