Since i've been back down to school I have neglected my tank slightly compared to usual maintenance because of school work. During this time something has some what taken over in my tank. The best i can describe them as are long brown threadlike worms... maybe? In any case, they are starting to cover all my corals (mostly softies and zoas) and keeping them from coming out completely, if at all. Any ideas of what they might be? I can't get a clear picture with my camera. Also what can I do about them? I have a reef dip it that helps.
