I checked out my tank today around 2+am with a flash light to see what's been munching on my acan colony chalice looking acan. To see this long brown stretched out tube worm looking thing munching away it's very thin it comes out of a small hole on the rock any one know what the F this is and what I can do to kill this thing since it gave me the right for killing my coral. It stretches over 3" to get to the coral and retracts quickly once there is light.
Look exactly like this predator
