Sea Urchin 24 gal?

[icepick5587]

I've successfully kept a common short spine urchin in my tank, but it kept knocking down my frags so I had to give it away. Now that my frags have grown out and are glued down... and I have excess algea... I was thinking about getting a long-spine urchin (Diadema). Does anybody have any suggestions or experience with these in nano aqauriums?

I have one, he has been banished to my sump.

Though interesting to watch it was brutal at pulling things out of the rocks. Even some glued down frags - maybe they weren't set in hard enough.

I ended up hating mine and rolled my eyes whenever it started to come out. However, if it wasn't ruining my aquascaping it would have been alright.

If you think everything is nailed down go for it, otherwise skip over these guys.

Sorry - I had a short spine, NOT a long spine.
