Sea urchin hitchhiker

[NormanB]

Hi everyone, got my rock in yesterday from KP Aquatics (great rock!) and there was a small urchin in a hole.

I can't post a pic right now, however I'll do my best to describe it.

About the size of a half dollar, body is black with short stubby brown spines and the spines have black tips.

It's currently in the sump, but would love to move it to the DT if it's a keeper.

Thanks so much!!

I’m not even sure if there are any “bad” urchins. Bulldozers aside.....

and i agree with jon, i don't know if there are any "bad" urchins.

Thanks for you quick reply Jon.

I see that KP Aquatics sell a brown short spine urchin, so I guess it's going into the DT.

Thanks for the confirmations on my hitchhiker!!

This place is great!!

It could be a pencil urchin...it does look exactly what is listed on KP Aquatics site.
