Aiptasia? Hope not....

So this little dude just appeared on my wave maker maybe a week or so ago. It's tiny, sorry for the bad iPhone pics. It will retract when gently prodded. It looks whiter than aiptasia, but I've only seen big ones on live rock at a local pet store. I've never had any in my tank. The tank has been cycled for 6 or 7 months now.

Hard to tell but may be a feather duster.

I do have a handful of tiny feather dusters in the tank, but this guy looks different. It looks less like feathers and more like tentacles. I suppose it could be a different type though. It is nowhere near as skittish as my other little feather dusters. I am going to try to get a better picture with my "real" camera when I get home from work.

I have some of those in my tank. Same exact thing. They're completely harmless.
