So I've had this pincushion urchin for about a year now and he's really entertaining to watch believe it or not, and does a great job as part of my cuc. But recently he started this new thing where he likes to sit on top of my new frags that I have on a frag rack. I keep moving him and he just keeps coming back so I'm debating moving him to the fuge while I'm on vacation so he doesn't irritate anything to much. Usually every day I come home from work he's just sitting on top of my new zoas and I'm not really seeing much growth and its probably because hes irritating them. Anyone else have similar experiences with these guys? I love to watch him fly around the tank but I really think hes limiting the growth of all my zoas. Thanks
