Anemone? Please ID

[cjsiii]

The first 2 pictures are of the same thing, just different angles.
It appeared on my bubble coral.
In the 2nd picture you can see the size of it.
It is aprox 3/4 of an inch tall.
And the 3rd picture is.....?
It appeared about 3 weeks ago on a piece of live rock.
It measures about 1/2"
Thanks for help!

The first 2 are sponges or tunicates hard to tell. The second is a coral of some sort looks to be a fungia. Good as well.

 

[cjsiii]

Are either of them harmful?

 

[mr.clownfish]

no.

 

[renogaw]

is it a fungia (hard base) or maybe a hairy mushroom (soft base)?

I agree the thing in the first two photos is a sponge. The third is definitely a coral. It could be a Fungia, or possibly a Hydnophora.
