Favia identification

[N3mo]

Hi Guys

I have these favias, or I was told they are.

What are they if not favias?
Do they play nicely with each other?
Can I place them next to each other in a favia garden?

I think it really depends on the favia. Some will sting each other, some won't.

Trying to figure out if he above will sting each other.

Currently I have acans stinging each other and candy canes stinging each other.
