Feather duster worms

[Mistablitz]

I guys I recently bought a feather duster worm a large Hawaiian one..I have another one that I have had a few months which I have place standing upright..the new one is also standing upright but it is much bigger around 5 inch diameter..my problem is that the new one is rocking up and down about 5ml up and down with the current...he is on the crushed coral between 2 bits of live rock ..we he eventually anchor to it or should I lay him down...he spends most of the day out and retract alot looks healthy I'm just worried he will leave his tube .?? Any help will be greatly appreciated
