Feather Dusters
Feather Dusters are beautiful and hardy sessile filter feeders. They are very appealing to the hobbyists due to their unique structure and fan-like cilias. Like any invertebrate, they need higher salinity than fish, and they don't tolerate copper at all. Most aquarists should have no problem keeping these alive in their aquarium with no special attention, as feathers will usually get enough food from fish waste and fine food particles. Nevertheless, for best health and growth, weekly feedings with a small particle food, like zooplankton, is recommended. When stressed or frightened, the Feather Duster will retract into its tube for protection. Also, do not be alarmed if you see this worm outside of its tube, because they will occasionally leave it for a better location with a stronger current. They can build a transparent tube in a few hours and will use detritus and sand to coat that tube.
