do feather dusters retract?
i noticed i have a red looking apitasia, that retreated in the rock, but than i noticed a tube i have never seen before. I had my tank a year, and i inspect it weekly, i was shocked to see a red feather duster?, which is extremely tiny. The tube part of it, was not here a few weeks ago, or maybe i just didnt notice it, but is it possible to grow that fast? I dont think i would miss something as big as it is now(the tube part)
i hear they do not grow bigger, but how will i know if it will stay small or be a bigger one
