Feather Worms Don't Come Out Anymore

[Schooner]

I don't know the specific name, but I have 5-7 'feather worms' sized up to about an inch in size that have always been out of the rock for the last 6-8 months. Recently, when they do come out (hardly ever) they look a little limp. I do regular water changes and I've checked the water chemistry and it is all within the correct range (I don't have the specific readings with me but from memory pH 8.0-8.3, alkalinity 120 mg/l, salt 1.022, NO2, NO3, NH3 all ok).

The only change is my alkalinity use to be fairly high, around 140-180 mg/L and it has since lowered (on it's own???) to 120 mg/L.

Anyone have any ideas as to why this is happening.

Probably not an issue but your salinity is lower than what I normally see listed here. Usually 1.025 or 1.026 for reefs. Also, possibly what they were feeding off has been depleted over the months due to "cleaner" water conditions or just lack of natural replinishment. What do you feed? Maybe a "worm expert" will chime in

Did you add anything that might pester them on constant basis? e.g. snails, hermits, crabs, blenny or ...........butterfly?

I don't know, just guessing. I have tankfull of those annoying white feather dusters. Never seen them in stress, ever!!
