Feather Duster Worm Fact Sheet

feather duster wormFeather Duster is a type of Marine Tube Worm (also call fanworms) that makes great addition to your collection of aquarium invertebrates. These mysterious tube dwelling species sometimes appear out of nowhere living on the surface or most of the time, well hidden under the live rocks and sands in the marine system. They demand almost nothing from the aquarist and most of the time will even take care of themselves without any intervention or special treatment. Their lighting requirement is similar as the one that you use to maintain a reef system and they even get their foods by filtering through the leftover debris present in the moving waters. Perhaps the largest threat to their survival in the marine tank is only from predation coming from the host of aquarium fish itself.

The anatomy of these fanworms varies according to species with some appearing in clusters form while others are single sprout and then branched out with different tentacle patterns. Other notable way to identify them is to look at the coloration which can be found in multicolored form often combining white, red, yellow, brown, blue or even black. Feather duster worms under normal condition will emerge and display an attractive tentacle opening and although this seems to project a threatening image to the unsuspecting aquarist, in actual fact, these worms are completely harmless in nature. If they get disturbed or they sense danger lurking nearby, they will quickly to retreat and seek refuge in their soft tubes. At times when the surrounding environment is deemed unsuitable for their liking, these worms can even migrate and abandon their tubes and then regenerate a new one at another location. They are not territorial and there is no evidence to point that these worms can turn aggressive and fight among themselves when under condition of stress especially in a crowded reef tank.

Most species of the feather duster worms are known to survive for years in the marine systems provided that there are plenty of hiding spots that allow them to burrow safe away from the attention of predators. Although the reproduction strategies can vary with some replicating asexually by cells division, others will reproduce sexually, and overall in an ideal condition, they can replicate and increase their numbers quite fast. These worms are also hardy in nature surviving under different water conditions including fluctuation of temperature, salinity and to certain extent moderate nitrate levels. One word of caution though, just make sure that they remain fully submerged in the saltwater all the time and never expose them to air especially when you are lowering the water levels during routine tank cleaning maintenance. If there’s a need to them to transfer your invertebrates to another aquarium, just make sure that you collect them in a bucket of water lowered into the enclosure or else catching them using fish nets which expose them to air will cause these fanworms to develop air pockets in the tube which can be life-threatening.

Feather duster worms can be bought in almost all saltwater aquarium pet shops and you could even get your new stock from fellow aquarists who are kind enough to spare some for you. Most of the times, the little fellas will actually arrive together with your live rocks but sometimes they don't appear at all and this actually depends on how the live rocks are cured. So the next time if you see these little guys appearing in the tank, don't get alarmed or attempt to remove them for fear of harm being done to your reef system because apart from your marine shrimps, these fellas should make another nice addition to your host of cleanup crew.

About Me

My Photo

My fascination and interest towards aquarium fish has led me to devote my time towards caring and learning about this wonderful pet.

Aquarium fish keeping is a very challenging and exciting hobby. When I first started, I never knew much or have the necessary guidance back then because none of my family members were actually a keen hobbyist. And because of that, I’ve encountered numerous failures and the worst part is having to deal with dead fish every time when you started to grow fond and getting attached to my pets. However, I persevered and took steps to find out and search for information from other hobbyist, apart from the knowledge gained and learned from my own experience and research. The blog that I’ve created here is meant to share useful information and tips about aquarium fish keeping so that new hobbyist will not make the same mistakes that I’ve made in the past."
