Is this some sort of anemone?

So I was checking my nano out right after lights out. Something caught my eye and I turned the lights back on to get some pics.
This was on my LR, back in the corner of the tank, so I couldnt get really good pics, because the nano is in a corner, so it was kinda difficult.
Some of the pics are blurry but hopefully they are good enough for an ID.

The thing is pretty much clear, except for the middle which is white, and then the rounded ball tips which were white too.

Its not very big, and the first time I have ever noticed it. Any ideas of what it is?

 

Its sort of an anemone. Well, I guess technically yes, it is an anemone. Anyway, its a mushroom polyp. Very great little hitchhiker to get. It will likely multiply and make a beautiful little colony. I love mushrooms so congrats.

 

No, I think they are talking about what is to the LEFT of the mushroom.
It does look like some form of anemone, but I have no idea what kind specifically.

 

Oh, Im not talking about the mushroom in the back of the pics, dont know how he ended up back there, great spot right? Im talking about the clear and white almost spiderweb looking thing.

 

If it is an anemone, how come its only extending at night? I have never noticed it in the light

 

it kinda looks like an anemone, trying feeding it with a turkey baster and see if it eats

 

Its real small, so should I try phyto or rotifers or something else

 

Is there some kind of anemone species Id website I can look into?
