Looking at my sun coral I found a strange creature. It's mostly inside what looks like a wormcast on the sun coral, emerging a little to feed I think. I can only see about 2 to 3mm of it, about 4 to 5 tenticles, purple in color with lighter tips, like a little squid. It seems to give of a sticky substance that catches particals floating by. It then draws this into what I presume is its mouth. It also has two tiny ring markings on it. I cant get my camera to focus on it. if any fish gets near it retreats into its tube. Any ideas
