I got 4 feather dusters, 2 of them which are always burried in the sand, they ve been there so long, theyve attatched themselves to the rocks and sand surrounding them.
That tells me they are comfortable there, only when I see them move from place to play, they arent happy where they are.
I set them in shady areas, underneath rocks, or far past where the current ends.
They just filter feed the phyto I feed the tank on a daily basis, sometimes I dont even feed them anything, and they are real savages I tell you
