What are these corals

[stravelstead]

My tank was set up on February 13. It went through the cycle and I added two clowns and a blue tang. I recently acquired this coral I have no idea what it’s called and I don’t know how to take care of it can you please help me?

Duncan, heteroxenia and green star polyps are my guesses.

Duncan, Kenya tree, gsp (green star polyps)
It’s better to isolate the gsp as it can become very invasive
