Hey y'all! I remember seeing an incredible photo of someone who had loads of feathers worms lining their sand bed, but I cant find it! Does anyone have any similar photos? I think they multiplied by themselves.
No photos, but I had a ton that I inherited in sandbed, and they certainly multiplied. They then vanished as soon as I bought a CBB for aiptasia treatment (the feather dusters went first, and then the aiptasia).
