Here's some info that Ron Shimek writes about feeding feather dusters:
"First, let's consider the larger feather duster worms. Although commonly sold, these animals are very difficult to keep alive in a reef tank; read that statement as, "They are impossible for all but the most dedicated of reef aquarists to keep." They need large amounts of very small particulate matter added more-or-less continuously in low densities in the proper non-turbulent conditions. Most aquarists do not/can not add sufficient food to keep them alive. Consequently, they will live for a few months in a tank, and then shed their tentacle crown, shrink and regrow a new crown. So, they then extend out of their tube, as a smaller version of their former self. This behavior is a response to starvation. They may do it one more time, but generally after about the second try, they simply die, having starved to death.
Some smaller feather dusters have different requirements and some species, with crowns about 1 cm (3/8th in) across do fairly well in some tanks as long as they get a lot of food."
I've personally never had luck with larger ones like the hawaiian dusters as they seem to follow the exact pattern that Ron Shimek says here. Although I will say that marine foods have come a long way since I last tried them.
The little hitch-hikers that come on liverock seem to survive through anything. I literally ignored my tank for a year and only kept it running but only did top-offs once a month and never did a water change..then I dismantled and set the tank up in a new house and MIXED THE SALTWATER IN THE TANK rather than in a seperate container with the liverock/sand because I figured nothing would be alive...Hermits, bristleworms, and FEATHER DUSTERS survived.
Good luck. Others have suggested there is hope and maybe you'll find their luck.
I read the same book, that’s where I got the info on the crown falling off and re-growing smaller because of starvation.
I fed my tank that Kent's microvert it was cheap and everything thrived on it. I have moved onto other foods but every once in a while I buy some of the Kents again. I also over feed my tank so algae will grow for my critters to eat, (I let algae grow on the sides and back of my tank) they mow it down as fast as it grows. Most likely why the big feather dusters thrived in my tank, the coco worms are more delicate I think.
