Hello just got a new ninja star snail and noticed a large tube worm is on it. It is hard and when out of the tube looks like a feather duster. Does this look like a feather duster? Should I leave this on the snail or could it harm my corals and fish? Also, not sure what is at the end of the tube but it looks like eggs of some sort. Anyone have any idea what this is? Not sure if I should remove the snail or leave it. I don’t have a qt tank. Thanks
