Assume you have coraline? I have a black longspine. I would stay away from pencil or pincushion as they are more likely to disrtub rock work and the pin cushion can strip down the coraline pretty quick.

HTH,

Thanks Aaron. I will consider that.

I have a Pincushion Urchin, Blue Tuxedo (Mespilia globulus) from liveaquaria.com. Makes a interesting addition and a fair alge cleaner. Has been known to pickup zoos.

Thanks for the info Ezy

I also have a black/purple pincushion. Nasty little bugger.

Eats bad algaes and what not, but also strips the rocks clean of everything. Nice coralline and green algaes last three seconds with that thing. Also pokes into soft corals a lot.

Maybe I need to rethink this.

I have had one black and one brown urchin since July and they seem to be doing well. I don't see them too often then tho, as they are behind the rocks most of the time.

Funny thing when I first place them on the bottom of the tank, they were following each other for a while and then went their seperate ways.

Thanks Serge. I`ve heard they are night creatures

I have two purple urchins that I acquired with my liverock. It loves munching on my coraling, will not touch hair algae, and is a real nuisance with knocking over corals and munching on the leather corals I (tried) to keep in the tank. I can only vouch for the purples, as that is all I've owned. They are great grazers though, althought mine won't touch hair algae.
