Feather Duster broken in half

Was wondering if anyone has had a feather duster break completely in half? It's a clean break, not ragged as though something else tried to break into his tube. Can't tell if he's in there or not. Had him about a month or so and seemed fine, staying open quite a bit and expelling poop packet. He was anchored pretty good in the sand and kind of leaning over a small rubble type rock. This morning he was broke about where he was leaning on the rock. Also of interest, another feather duster located elsewhere in the tank, was turned completely around and under a small rock overhang. He was orginally located just outside of the overhang and my starcki damsel like to hide behind him under the overhang. The duster didn't seem to mind and wouldn't even duck in his tube when the damel was around. I've only had that duster about a week but he seems fine as well. He's not as well anchored as the other one. Since becoming rotated I have not noticed him out quite as much. Should I put him back or leave him under the overhang? Something seems to have happend overnight. Any thoughts, suggestions and comments would be appreciated. Thanks.

 

sometimes feathers will bail out of there old tubes.did the worm it self break or did the crown just fall off? what else do you have in your tank(fish)? and what are your param?

 

I have a flame angel, starcki damsel, two true perc clowns, cleaner shrimp, 3 black footed snails, 3 nassarius snails, green emerald crab, 12 assorted small hermit crabs in my 38 gallon tank. No nitrities or amonia, nitrates around 80 (doing water change today), SG of 1.023, temp of 78, ph at 8.0 (added buffer the other night), calcium of 420, kh of 10, phos of .25.

 

Angels will eat feather dusters. Not sure that's what happened but usually angels and feathers dont mix well.

 

Personally I'd rehome about 11 of those hermits they nuttin but trouble! Lol all 12 probably ganged up on the poor duster and broke it in half :0

 

Good news! Feather duster is alive and well. He came out last night to eat. Not sure what happened but he seems fine as well as the other duster who seems fine under the rock overhang. Thanks to everyone.
