i have about 300 tiny little fan worm like things in my 10 gallon nano. they are whitish almost clear and the head is about the size of this >.< i dont know what they are. i had some feather dusters in there, but never had them reproduce (or atleast havent seen any new ones in any of my other tanks. thi same LR has been in 3 of my tanks but this is the only one with these tiny things in it. any ideas? it looks just like a tiny feather dusters or rock anemone (aiptasia)
