Bispira feather dusters are smaller cousins of Sabellastarte feather dusters - more delicate crown structure with finer feathers and often more vibrant coloration (purple, red, yellow, white). Form clusters in the wild and tolerate density in captive setups. Smaller adult size makes them well-suited to nano reef systems.
Native range: Indo-Pacific. Most US trade specimens come through marine wholesale suppliers in Indonesia, the Philippines, Hawaii, and the Caribbean. Wild collection remains the primary sourcing method for the majority of marine inverts - few are captive-bred at commercial scale. Quality of acclimation at the wholesale/retail stage is the biggest single predictor of long-term survival in home aquaria.
Tank size: 20 gallons. Parameters: temperature 76-82°F, salinity 1.024-1.026, plus the standard reef tank requirements - stable calcium 420-440 ppm, alkalinity 8-10 dKH, magnesium 1300-1400 ppm, nitrate under 25 ppm, phosphate under 0.05 ppm. The species requires conditions consistent with a healthy reef tank rather than nutrient-stripped sterile water - well-established systems with diverse microfauna and biofilm typically support these inverts better than newly-cycled tanks.
Lighting: depends on species. Photosynthetic inverts (clams, anemone-symbiotic species) require high-PAR reef LED lighting. Filter-feeders (worms, scallops) prefer moderate lighting and benefit from particulate-rich water. Flow: moderate, indirect flow works for most inverts - direct high-velocity flow stresses or damages soft-bodied species.
Acclimation: drip acclimate over 2-4 hours for hardy species, 4-8 hours for sensitive species (Linckia stars, sea hares, demanding nudibranchs). Never expose inverts to air during transfer - capture in a bowl underwater and transfer wet.
Bispira Feather Duster diet: Filter feeder. Feeding strategy depends on dietary type. Algae eaters require established tanks with biofilm and microalgae growth - new tanks lack the algal base they need. Carnivore inverts (starfish, some snails) need targeted meaty feedings 2-3x weekly. Filter feeders (clams, worms, scallops) need phytoplankton in the water column. Photosynthetic species need adequate lighting plus supplemental amino acid or coral food dosing.
Safe: Peaceful reef community.
Avoid: Crown-nippers, copper meds.
Asexual fission in mature tanks.
Crown loss; flow sensitivity (less tolerant of strong flow than Sabellastarte).
Smaller, more delicate, more colorful crown. Tendency to cluster vs. solitary placement.
Possibly - mature healthy specimens occasionally split asexually, producing small clusters over months.
$15-30 each. Sold individually or as clusters.
Yes - they tolerate density and form natural-looking clusters when given adequate space.
