Who has urchins?

[CATALYST]

And what kind?

 

[Anselth]

We have a blue tuxedo urchin. Really good at scouring back some of the corraline algae. Doesn't bother the corals except when it decides to carry around a frag as campflage.

I have a black spiny urchin that came as a HH. It hasn't caused any problems, yet. It trucks around eating the coraline algae and helps to spread the spores, I say.

I also have a blue tuxedo urchin. He will knock things over on occasion, but I do not have any real problems with him.

I have a red pencil urchin. He hides most of the time.

I had a Black Longspine Urchin {Diadema setosum} excellent herbivore but it just grew too large and I removed it. Now I have a Blue Tuxedo Urchin {Mespilia globulus} and will probably add another one soon.

most urchins are labeled "Reef safe; with caution". They are algae eaters but may occasionally stray for a sessile invert. Rock boring urchins will bore a hole in the LR to live in and come out at night, actually most are nocturnal. Long spine black urchins should be kept with extreme caution due to their venemous spines and their habit of eating sessile inverts such as sponges and corals. The Tuxedo and Pencil urchins are excellent candidates, just pay attention to it's eating habits. The word "Urchin" comes from an Old English word which means "Hedgehog" which urchins resemble! HTH.

Long spines get to 15+", so not them!! Tuxedos stay the smallest, less than 3", rock borers and pencils around 4".
