FeatherDuster lost its crown

[CaptainK]

Yup just like the title says, came home yesterday and my featherduster had been beheaded.
Now I know that this is either a sign of stress, or reproduction...I think.
The tube that it left behind is still in tact and is still standing up, is this a good sign?
All of my tank parameters are fine, so if this is a sign of reproduction are there things I can look for?
Thanks,
CaptK

The crown will grow back...(my small feathers loose them all the toime, dont know why though)

I bought a feather with one crown, and now it has two!
