Name that Coral

[reefing.on.reefer]

So I was gifted to corals by a gentleman getting out of the hobby. I acclimated them and placed them in the tank together not realizing how big they actually were.

the polyps look similar in shape, size, and texture.

my question is. Can anyone name them for my own reference. And also will the sting eachother if polyps touch.?

Maybe bubble corals, hard to identify under blues.
