clownfish diseases

[spawn]

I've recently added some red mushrooms and I think they seem to want to host in them. Would mushrooms do this, I don't have many or do I see them around Zoa's. Sps dominated tank. If this is the problem, is it very harmful with any serious effects?

my one clown randomly got spots on him too . There wernt any corals in my tank to sting him , so i dont know where they came from . but hes had them for 6 months now and is fine so i wouldent worry too much about it.
