FAQ
Frequently Asked Questions
Yes, distantly. Both are in the phylum Annelida (segmented worms), but feather-duster worms are marine polychaetes, a very different class from terrestrial earthworms.
Yes, they are popular in saltwater reef and marine aquariums. They require stable water conditions, appropriate food (plankton/ dissolved organic matter), and should not be kept with aggressive fish that may nip their delicate crowns.
It can cast off (autotomize) its crown due to stress, poor water quality, or predation attempts. If the worm itself is healthy, it can often regenerate a new, though sometimes smaller, crown over time.
In the context of marine aquariums and informal biological discussion, 'feather duster' is a very common shorthand. In formal scientific writing, the full term or the family/genus name is preferred.
