I have read how difficult it is to keep a blue linckia sea star, where a well established aquarium plays a big role, and some people have had success keeping them alive. Does the presence of asterina stars (whether wanted or not) indicate that conditions may also be favorable to keeping a blue linckia alive, or are the two completely unrelated? Not that anyone wants to admit lack of success, but has anyone had a lot of asterina stars in their tank, yet still have blue linckias fail to thrive?
