Mushrooms and acans touch?

[mushy coral]

My rockwork have this open area with no coral on it and im thinking of putting my acan there (space above purple circle in image). However there are red discosoma below and i believe they gonna start to grow up toward that space so i want to make sure that they dont sting my acans. I will also put a purple monti cap in the purple circle in the image so will monticap and discosoma get along? And i also want to put the ricordea florida in with the acans too, can they touch? Thanks!

Mushrooms don’t sting SPS or LPS. No they can’t touch, because they need to grow out.

Coral aggression is “a real and present danger”.
