Maybe an Eunicid polychaete?

I had one of those and it definatly wasnt a bristle worm, it looked more like a centipede it made tubes by using the substrate and kind of glued it together and it would move through the tubes. It seemed to always build the tubes around my green stars and then I found out why! It was eating them, It is no longer with us ^_^ Rest in Peace <_<

i have been reading about the polychaetes and i believe it is, althogh i think as best as i can tell ut is a clamworm. the research varies greatly though, for instance one source says 5400 species of polychaete, where another quotes "more than 8000 species". But anyway it is in the bristle worm arena, and whether fortunately or unfortunately down in my ceptic tank.

Thanks to all for the input!!
