Feather dusters in the sump, out of control

[lastlight]

The annoying plague-like ones I've always had were the ones with hard white tubes. I used to go around my display every now and then and just shatter them all. They make the rock all sharp too and silly me thought the fish could even be scraping on them. I just don't like the way they look. If they're messing with your husbandry then axe'em =)
