So I have 2 brittle star fish in my refigium. I've been putting off adding them to my display. Ones a black banded brittle star and ones a redish orange color. Does anyone else have one in their reef tank? I use to have one in my old tank but not in my current tank. I read online that they are reef safe but could attack small slowing moving fish. Should I be worried about anything as long as they stay well fed?
