Do gonipora fight each other?

[Myrdin Potter]

I have 4 gonipora frags (one a huge colony) and I am wondering if the polyps brush against each other will that start some form of warfare? I can space them a little further apart, but depending on the water flow and the extension, still a rick of some small contact.
