Help...feather duster sick?

[texasdivegal]

I have 3 feather dusters in my tank. They have been in the family 6 months now and have been doing really really well. None of them have lost any feathers or jumped out of their tubes...but....

I have notice that they won't go back into the tube when startled. I found one on the bottom the tank. I picked it up and it didn't even move. Now there is brown globs around the openings? It doesn't look like the normal waste? Are they sick?

What should I do?

Water
PO4 .1
Ph 8.4
NO2 0
nh 0
NO3 0
SPG 1.023

Nothing has changed in the tank in 4 months. I do water changes often. Everything else is doing great.

Maybe the coral beauty has been picking on them. The attached says they can.

Any change since first posted?

No changes since post. They look great but not reactive. I have not seen the beauty messing with them ever. I just don't get!
