I love my Pencil urchin and I have semi-reef with allot of interlocking rockwork and some corals not epoxied to rock. I have not had any issues with my guy and he is pretty sizeable in a 55gal.

But each specimen is different and I am lucky so far.

As for the coraline algae, yeah, I can tell where he has been, but it grows back pretty quickly and doesn't really phase the look of my tank. I just wish he would eat the coraline off the glass, LOL. But from what I have read, the urchin actually helps to spread coraline algae thoughout the tank b/c their droppings still have the algae in it and it starts to grow as well.

Anyway, to each his own, I was too much of a wimp for the Long Spine urchin, and liked the look of the Pencil. Looks to me like something from another planet.

Enjoy, I would recommend one.

I just wanted to add that I have 2 purple urchins (common urchins) in my tank, that I sorta wish I never acquired. Mine loves leather corals, and I see him all the time perched up on top of my frag, rasping away at it. When he gets off, there is a nice little white spot on the top of it. I've also noticed it cruising through my yellow polyps and zoos. My tank is practically devoid of coraline algae, and unless I triple epoxy something to the rock, it's coming off beause of my klutzy urchins. The other night, I found it chugging away over my new ricordea polyp.

So my advice, stay away from the purple urchins. And if anybody has a FOWLR tank and wants one, just let me know. lol.
