I haven't put anything in the tank for almost a year and a few of these have appeared over the last week or so..

Asterina stars. They reproduce pretty easily in our reefs. Some people start reducing the population if they get out of hand. Some also claim they much on zoas, but I've never had a problem with them.

Thank you. I couldn't find them in any of the books I have.
