Care guide, husbandry, breeding, disease, sourcing, and tankmate intelligence on Feather Duster Worm - written by the Fast Aquatics editorial team and cross-verified against vendor records on the live marketplace.
Feather Duster Worm (Sabellastarte spp.) is a marine invertebrate kept by aquarists for reef-tank cleanup, biological control of pests, or aesthetic display. Hardy and forgiving of typical beginner mistakes when given proper water chemistry.
Where Feather Duster Worm comes from
Feather Duster Worm (Sabellastarte spp.) is native to Indo-Pacific reef ecosystems, with wild populations distributed across coral reefs, sandy lagoons, and rocky tide pools. Captive specimens are typically wild-collected; some species are starting to be aquacultured but most Feather Duster Worm sold today still comes from wild reef collection. Sustainable sourcing matters - look for vendors who can verify their collection practices, and consider aquacultured alternatives when available.
Feather Duster Worm tank size and setup
Feather Duster Worm requires a minimum of 20 gallons for healthy adults. The minimum is based on the species' adult size (6 inch crown), territorial range, and behavior pattern. Most Feather Duster Worm sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Feather Duster Worm setup: mature reef tank with stable parameters, live rock for cover, sandbed substrate (1-2"), reef-grade lighting if photosynthetic, and a fully-cycled biological filter at least 6 weeks old. Newly-cycled tanks under 6 weeks crash the parameters that Feather Duster Worm depends on.
Feather Duster Worm requires standard reef parameters held tightly stable: Temperature: 76-80°F (24-27°C) Specific gravity: 1.025 (refractometer-measured) pH: 8.1-8.4 Alkalinity: 8-9 dKH Calcium: 420-450 ppm Magnesium: 1300-1400 ppm Ammonia + nitrite: Both 0 ppm Nitrate: Under 10 ppm Copper: 0 (lethal to invertebrates)
Feather Duster Worm is sensitive to copper - never medicate the display tank with copper if Feather Duster Worm is present. Stable parameters beat perfect parameters.
What Feather Duster Worm eats
Feather Duster Worm is a plankton filter feeder. Filter-feeds on suspended plankton and dissolved organics. Target-feed live phytoplankton, rotifers, or commercial reef foods (Reef Roids, Coral Frenzy) 2-3x weekly to ensure adequate nutrition. Feed Feather Duster Worm appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Feather Duster Worm tankmates and compatibility
Feather Duster Worm is generally peaceful and compatible with most reef community species. Avoid keeping with predatory fish that view inverts as food: large wrasses (especially halichoeres + thalassoma), triggerfish, pufferfish, and certain large angelfish. Multiple Feather Duster Worm can share a tank but compete for food.

Feather Duster Worm adult size and lifespan
Feather Duster Worm reaches 6 inch crown at adulthood with a captive lifespan of 3-7 years with proper care. Many marine inverts molt periodically; provide adequate calcium and a stable parameter regime to support healthy molts.
Can you breed Feather Duster Worm?
Feather Duster Worm breeding in captivity ranges from straightforward (some shrimp, snails) to nearly impossible (most starfish, urchins) due to pelagic larval requirements. Captive-bred specimens are increasingly available from sustainable aquaculture facilities; check with vendors before assuming wild-caught origin.
Common Feather Duster Worm diseases and problems
Feather Duster Worm is sensitive to copper, ammonia spikes, low oxygen, and rapid parameter swings. NEVER use copper medications in a tank with Feather Duster Worm. Symptoms of stress: reclusive behavior, color loss, refusal to feed, abnormal molting (incomplete or stuck molts). Most Feather Duster Worm deaths trace back to acclimation shock or parameter mismatch - drip-acclimate over 45-60 minutes when adding to a new tank.
