I bought a tuxedo urchin because I think they're awesomely cool and my LFS had them in stock for the first time I can remember. However, I don't have any algae haha. I have some nori, but I cannot for the life of me figure out how to feed it. It never finds the nori clip, and if I try to place the nori near the urchin it either just leaves it alone or grabs it and wears it as a hat. I don't want it to starve! Any thoughts?
