Came home Saturday afternoon and found one of my large (3"+ crown) feather duster worms sticking about 4" out of his tube. Sunday I saw his crown laying by a rock, but can't see if the worm has left the tube or if he's just shed his crown. Why would he expose his "worm" part? All water parameters, corals, fish, inverts, other dusters, etc. doing great. Any ideas/info?
Thanks
