Hammer & Duncan placement

[Auroraz]

Are these three corals (Duncan, Hammer, and I’m not sure about the third - please help identify it ) placed too close together?

They’re doing really well, and I don’t want to mess with something that’s working nicely - but it might be getting a bit too dense..

For reference, here’s how they looked just three months ago:

It’s hard to determine distance based on the picture but make sure there is at least 6” between polyps. None of the three will play nice with each other. The torch on the left will win the war with the duncan and hammer. Eventually as they grow new heads and get bigger they will need to be moved.

Goniopora on the left. The Goniopora is capable of sending out some longer polyps with elongated stinging tentacles. The other two are more docile and will not attack too far away.
