Ricordea kill my sinulara?

i have a mass of rics growing around a sinularia and they have never caused it any problems. Is there any other leathers in the tank that are nearby?
 
I've got a few zoanthids on the other side of the tank that are growing with an actinodiscus mushroom. The sinulara is the only leather by the ricordeas. The ricordeas and sinulara are growing towards my dendros and clove polyps though. They will probably come into contact with them in a year.
 
A yuma I have tore into an elegance, destroyed half a war coral, and killed part of a chalice. My florida rics cannot seem to hurt zoas but did irritate a duncan enough to kill part of it. I don't really have any leathers, so no advice there, but watch them around LPS
