The Feather Duster is a great addition to any tank. They don't require any care and are great to watch. A worm lives within the tan tube of the Feather Duster, and this worm carries a colorful "crown" of feathers. These feathers are pushed up through the opening of the tube and act as a catching device for food, which is collected by the worm's mouth at the base of the feathers. The worm uses the tube as protection and will quickly pull in the feathered crown when it detects a predator. The Feather Duster can be placed on the substrate or into your rockwork. The Feather Duster will attach its foot and remain stable once placed into the aquarium.Feather Dusters are not often thought of as worms because what most people see is just the pretty feathery "crown" the worm inside uses to capture food. But there truly is a worm living inside the tan tubes they create, using sand and secretion to create as their home. The feathery crown is also called a "radiole" and is used as both gills and to bring food to its mouth which is at the center of that crown. Feather Dusters are very light sensitive and will quickly retract when approached or disturbed. Feather Dusters are known to "throw" their crowns which usually regrow within a few weeks.Feather Dusters are not often thought of as worms because what most people see is just the pretty feathery "crown" the worm uses to capture food. But there truly is a worm living inside the Feather Duster's tan tube. They create this tube by combining sand and a special secretion in order to protect their delicate body. The feathery crown, also called a "radiole", is an extention of the mouth of the worm and serves as both its gills and a way to capture food.
