Went to Naples, Fl today and my daughter brought home a sand dollar along with her collection of shells. Turns out he is still alive (about 2 inches across). Is this something I want in my reef? Anyone know what they live on etc.?
I was thinking about putting some in my tank (or at least refugium) as there were thousands around the jetties in June. By August, they were all gone. Wonder where they went? Nowhere real fast, that's for sure.
