hey guys:)
I have three urchins, two rock urchins and a long spine.

i rarely see the reef fellas as they are burried deep in the reef, but they have come out recently when i was shooting fish:)

here are some far away and some under flash close up, they do a great job on my corraline, but knock a rock or two over occasionaly.

urchins eat corraline and stuff, they are a bit clumsy though and climb over abo****ely everything, so maybe its not trying to eat it just moving about? as long as you dont see damage to it it should be fine

leave him in the sump for a little while, maybe let your leather recover a bit, it is very unusual, maybe check to see if something else has chomped the leather too? maybe the urchin was in the wrong place wrong time? anyway check the coral over the next few days, see if its recovering, if it gets worse then it may not be the urchins fault, but just check to make sure, if it is the urchin you may want it to remain in the sump, or swap it for an urchin that doesnt have a taste for your leather?
