Can anyone ID these?

Hey all, have these two little guys in my tank for a while. Growing slowly. They look peaceful and super neat, but after exhausting google and the web, I still cannot figure out what these are...any help greatly appreciated!

Corynactis anemones I believe. I have a couple and they don't really spread and I've read they're harmless.

Holy cow!!! Awesome. Thank you!!! This is totally it! I just googled that, and bam! Wikipedia did say that they can replicate both asexually (cloning) and sexually (polyp dispersion). They're also known as strawberry anemones. This is so cool!

I would have said pest nem and to kill it.
