Feather Dusters A-Go-Go

crappy shot but it's the only angle i have. these dusters have been multiplying in the shadow of the UGF tube (the monolith to the left). the tube is covered in tunicates (whiteish blur on top left), which relocated themselves from my LR fairly recently. the dusters have grown pretty fast with the abundant phyto and steady ca/alk i've been dosing.
