Mushroom agression

[GuilhermeLba]

I'm new to the salt water world, but I read that are 3 main types of mushroom, discusoma, rhodactis e riccordea (don't know about the corret spelling).
My doubt is all 3 of them can live together (Touching each other)?
If not, which one can stay together and which cant?
What about other types of non agressive corals, they can have a mushroom on their side?

Mushrooms (anemones) in my tank have never had an issue touching each other or other non aggressive corals. Only my large ritteri nem bothers them. It covers them not allowing for light. Oh and aiptasia bothers my rock nems
