I have 3 tiny elegance corals that have been with me for about 3 months. I noticed on 1 that it had small reddish brown spots on it that were at different locations as time passed. If I took my pinky nail and touched one of these spots I could scrape it off. Im assuming they are planarea or some other bug. I dipped the corals in Seachem reef dip but it doesn't seem to have done any good as they are still there and spreading to the other ones. What do I do to get these off?
