I have a bunch of these little featherduster type creatures that are growing on my LR. They are about 1/32" round and about .5" long. They have a red featherduster type fan on one side. If you move up to the tank slowly the fan will stay out, if you move fast they will retract the fan into the body.
My question is this what are they?, and are they good or bad. If they are bad what will eat them. I have a blue masked angel, yellow eyed tang, hippo tang, and a maroon clown in the tank. The tank is a 90 with 100lbs of LR. I have cleaner shrimp, porcelain crab, sally lightfoot, emerald crab, coral banded shrimp, hermits, turbo's, CC starfish, and a golden star. And probably a whole bunch I forgot.
Anyways nothing I have seems to be eating these creatures. What will? ;)

Those in the picture are alot larger than the ones in my tank. The fan is only a bright red on the ones I have. I've seen them for about a year and they don't get very big? The fan is only about 1/8"-1/4".
