feather duster blew its top
 

my wife came home with a feather duster about a week ago yesterday it blew its top and today i see 4 little feather dusters about the size of a dime in the rock close by, will the big 1 grow back or is that it

It takes some time, but they often grow back. I thought I had lost one of mine (about 2" dia). After about two weeks it started a small new crown, a month later and it's almost back to original size.

Sometimes if nitrates are too high they will shed the crown.

Or shrimp will pick at them as well.

Same with mine and it grew back...

Another reason this will happen is starvation.
Make sure you are target feeding it phytoplanketon daily or it will die.
Lack of feeding is the primary cause this species don't last.

I think the feather duster sheds its crown only when it feels life is in danger. By shedding the crown it would prevent the entire worm from being eaten or killed in the event of an attack. I don't think starvation was the cause for loss of crown because the duster uses that to collect food from the water. Spot feeding it with phyto is good. I had many feather dusters in my old tank and I fed them coral frenzy and phyto having great success. Feed it well and the crown should grow back in 3-4 weeks.

My picasso trigger ripped the crown off of my coco worm... I thought it was dead for sure, but it is growing it back now. Sad part is that I put the coco worm in the 90g to heal, and I did not know which fish had done it. I caught the trigger and put him down there with the coco worm... found the new crown on the bare bottom. It is back in the display regrowing again. Trigger has a new home.

Hope it makes it, and don't know how they feed without it. Is there anything that can be done to help it eat at this point in time?

+1. Not very good long-term survival on feather dusters. The ones that stay teeny that grow on the rocks and glass do really well though. I think it's just that the small ones have an easier time satisfying their nutritional needs.

thanks everyone
 

my duser is a large 1, she bought the biggest 1 in the store
