hitchhiker - not aptasia.. i dont think?

[Dreadful]

This part of the forum is always my favorite cause you never know what you'll find in your tank!

I've got some little guys in my tank.. started with only a few but they seem to have spread quite a bit over the last year or so. In my early stages in the hobby I had thought they were some sort of tube worm or feather duster or something. But now that I'm a more experienced hobbiest I believe them to be some type of anemone.

I'm pretty sure its not aptasia because they look a lot different and seem to not grow very large or be harmful in any way.

They remain fairly small so I cant seem to get a very good picture but the best way I can describe them is mostly clear in color but they have white dots at the end of their tentacles.

The closest picture I can find is this:

But its really not very close.. they are significantly smaller with no real visible color
