Galaxia (Galaxy) Corals. Can multiples be placed together?

[Injoynit]

Was looking at purchasing some but I know they can have stinging feeder tentacles up to 12" long.
Wanted to place a group of them on one side of my tank but was wondering if anyone has kept them in groups like hammer corals or if they will still sting each other?
Thanks!

From what I've read, same species coral are peaceful to one another
