Hitchhiking Coral ID

[Bento]

Hello,

I brought a frag to day and noticed another coral on the bottom of the frag when I was placing it on my tank.
I was wondering if anyone can help me ID it.
I'm thinking it looks like a rhodactus sp. Or possibly a mini maxi
Although that's just a guess.
I've attached photos below

Thanks for you time and help

Rhodactis, cool.
