okay one of my brittle stars has suddenly developed a crush on my remora protein skimmer (the black box part in the tank) I have had to dig the big boy out like 3 times in the last 2 days, I am beginning to wonder if it is exploring alternative lifestyles, I got some fine mesh to put over the top where he keeps climbing in and so far so good, but I really don't want to keep it there forever unless I have to. I'm afraid it would get rather messy unless I rinsed the mesh out daily. Anybody else every had horny brittle stars with their equipment before
