Here's a pic of the Zoanthids I bought from Oddballs this weekend. Still working photography.

Very nice, looks like your getting some good shots now with your camera. If I had to guess, you shot the photo at an angle from the glass, which sometimes causes the blue halos you see around some areas. I get them too on some shots, best way to reduce them is to shoot straight through the glass, though it's difficult sometimes to do that.
