help with feather dusters.

My tank is really filling up with miniature feather dusters. I mean a lot. It a 29 gallon tank. Can to many be a bad thing? Is it an infestation? Should I let them go or get rid of them? Don't seem to be hurting anything right now bit will they?

They're quite common and aren't harmful at all. Filter feeders. Don't worry about them. I have hundreds too. They look awesome when in massive clusters imo.
