FWE and small Tube Worms/Feather Dusters

[Psycho graphic]

A quick question, Will FWE harm small Feather Dusters and Tube Worms? I have read conflicting reviews on this. I have quite a few FD's and TB's that I don't want to lose as some of them are really nice looking. I have one small hard shell feather and one small purple duster I definately don't want to lose. I'm not talking about regular FD's, these are the tiny ones that grow out of the rock.

If FWE will kill them, could I do a FW dip on everything when I upgrade to my next tank without harming the FD's and TW's?

I know all about the needed syphoning of the FW's, WC's and Carbon to run afterwards, so no need to waste your time typing that info.

It has not affected them in my tank, and I've used it a few times at above the regular dose.
