ID help ... red tenticles

Hi,
We saw these red tenticles for the first time this evening.
Lights had been out for about 2 hours. The tenticles are just in front of a Kenya Tree stalk and beside a small snail shell.
They tried to attack a passing hermit crab.

There was no visible "body" to these tenticles.
Any idea what these "creatures from the deep" might be?

Thank you,
winland

My sentiments exactly...Terebelid worms(Polychaete) Great reef invert, IMO!

 

Thank you both for the speedy responses.
I was a bit worried that I might have something "nasty" inhabiting my 7 month old 125g reef tank.
One of the great things about this hobby... always learning and finding new and interesting creatures, day and night.

thanks again,
winland

 

It is amazing, yes, how many different life forms are associated within such a small area. More diverse than the Amazon River Basin, coral reefs(and our reef tanks) are simply unbelieveable with the plethera of different organisms many which we will never encounter as they are either very minute, or live within or under our live rock etc. and live secretive and cryptic lives!
Good stuff!

 

It looked like dinoflagellates at first, but your description and other responses change my thought.
