Any ID on these

Firstly I have this in my tank , first noticed it a couple of months ago, was very small, now anout the size of a R5 coin. It is the little round one underneath the blue damsel.



Another shot, it is in a bit of a difficult spot in tank to get good pic.

 

I would say that is a majano anemone

 

@JackSplat I am not quite sure, from the top it looks somewhat different. I'll try and get a pic from above.

 

Is that an old fungia plate coral skeleton it's growing out from?

 

@4age it is growing on a piece of "rock" I had quite a while. If it is a fungia skeleton it must have been a massive one.
It is quite a big piece and it has a pattern on that almost look like tree bark.
