Is this an anemone?

[Brennan32]

So when i got home tonight i turned on my tank lights to notice this clear creature with some tentacles I believe. And when i went to go get my mom to ask if she knew what it was it was gone so it must be nocturnal and i found about 6 of them before i went to get her all were pretty small any help would be great! Here is a pic of what it looked like it isn't my pic it's what i found on the internet but the pics website was no help to me
