Acclimatizing a tuxedo urchin

[foreveringlass]

I have not seen my urchin doing that, but I wouldn't doubt it! Mine searches for the strip I put in the sand for my sifting star, because I don't completely bury it. It some how manages to get a small chunk of nori stuck to it. Then slowly works it down to it's mouth. Let me know how yours does with the clip!
