Can apstasia be red?

[marcingo]

Hey.

I believe I have an aptasia growing out of a rock. I cannot get a picture since it is tiny and at a wierd angle that a camera would not catch. Basically it looks like cotton candyish very red top- not like the classic apstasia flower looking tentacles. It also seems like the stem is a calcerous hard stem. I havent touched it or anything. Could this be a worm or a feather duster? I have not seen it retract into the tube- but I know that some days I will look in the area and not see it and some days I will see it so Im guessing it does retract. Any ideas anyone, also any plans of action- I wouldnt mind leaving it but if it is aptasia I wouldnt want it to spread.

Thanks,
