Can anyone identify this amazing sight. Last night as I was spending time with my magnifying glass I came across this live rock that has a colony of a pair of transparent tenacles sweeping round the air and the rock. you could only see the tenacles appearing out of the tiny holes and most in pair, but I notice some on the sand but were covered in sand grain like it let it stick on itself whatever it is. however I manage to see what look like half a body sticking out in one end what appear like shrimp like and it was transparent with black stripy mark. the tenacles appear about 3-4cm long. Sorry could'nt take any photo as it was in the darker side of the tank plus the macro on my camera is'nt that good.
Thanks mate for the link. Found it to be spaghetti worm then and harmless which is good. Good to watch them though and today found one stretch out to 6" long and the link say it can stretch to 1 metre Imagine it creeping out of the tank and strangle me in my sleep
