So i have a few new heads coming out of my acan frag, but the frag is also littered with feather dusters. Will this bother the new heads from growing? The feather dusters have been multiplying like crazy on this frag and in my tank. Should i crush the ones on the frag or just leave them be? Also not sure how my post got tagged with "emergency" and now i don't know how to change it lol
