Picked up a gorgeous blue spot long-spine urchin yesterday. Never really paid attention to urchins before, but the neon lines on this one were unbelievable. Acclimated him and placed him into the tank and he seems very happy. Problem is his first foraging was on a "Zoa Mountain" and he munched on the first colony he came too -- roughly 8-10 heads. After that he continued up the rock and didn't disturb any other colony and he had to go over or pass about a dozen colonies before he left that rock and moved on. I can gauge his path pretty well. So the question is -- since he just ate the very first ones and ignored the rest -- should I worry? Should I remove him or just watch him? Should I have not gotten excited about the pretty colors and bought him?
