Since this is a topic often fraught with misinformation in the hobby I thought I would share my own story on the methods I've used to care for my feather stars. I received my first one a year and a half ago after many months of research and planning. I have found that they are not as difficult to keep as they are made out to be. I feed mine Benepets Reef Food, Reef chili, and Azox coral macro diet. I broadcast feed mine every day and they have responded well to it. I think the main reason they fail in tanks is because people either impulse buy them or they buy them and overdue it with chasing numbers which makes them sick or kills them. For filtration I only have a skimmer, no sump, no reactors of any kind and a 5% water change once a week. I realize that I am in a minority with keeping these successfully but I hope to dispel alot of the misinformation surrounding them since you can't really go by alot of what you read in this hobby.
