Sps with mushrooms?

Ive heard that mushrooms can harm SPS corals and that it might be a better idea to keep them separated? I have a few Sps corals in my 30 gallon tank along with some Florida Rics, Yuma Rics and one other mushroom. Should i be worried about the mushrooms spreading in the tank? Should i take the shrooms out and put them in my LPS and softies 14gal? What would you do if you had the option to transfer them? They are just in the sand bed now but will prolly try moving up the rocks soon

 

i know several people including my self that have sps with shrooms and nothing bad happened

 

sweet. I really like them and want them to thrive and spread but dont want any rivalries.
