Name the coral

[JLH-l3ioCub3]

Galaxy corals aren't that hard to keep from a husbandry point of view. The main concern with them is they can become an aggressive coral and can extend their stinger tentacles 6 to 8 inches (sometimes more), so their placement near other corals needs to be considered.

First off, thank you for taking the time to post all the good info.
Secondly, #2 is definitely what is in the first pic you posted(blue snowflake clove). I was doubtful it was Xenia because of the size of the polyp and length of the "stalk" in comparison. I just didn't know if there were different varieties of the species. Thank you for clarifying this! It's good to know what I have now.
As far as the galaxy. LFS did inform me that they sting so I did place them away from everything else. As it gets bigger I'll have to start fragging it to keep it that way!
Thanks again!
