Are clownfish hosting an anemone less likely to NOT get ich?

I have an outbreak of ich and my tank and almost every fish has ich. Tank has had ich for 2 weeks but some fish seem to not have been affected. The yellow tang and hippo has it the worst. Sailfin is larger and i think stresses the other 2.

Infected
Yellow tang, hippo tang, sailfin tang, orange spot goby, algae blenny

Died of ich - was a healthy and eating powder blue and was stressed by sailfin.

No ich
Pair of true perculas, mandarin, 3 bangai cardinals

The host anemone is a ritteri and its away from the sand. The cardinals are always hovering mid to higher part of the tank.


My thoughts on why they are not infected:
Wondering if ich has not infected some fish since they swim away from the sand.
Clownfish better protected from ich due to protective coating that prevents them from being eaten by anemone.
Little to no stress.

Most of the fish has been trapped and transferred to a hospital tank. Hippo, mandarin and clowns has stayed away from trap but still trying.

Don't forget to take into account stress. As you know stress can lower a fish's immune system, which makes them more susceptible to disease. Perhaps your clowns are happy and have a strong immune system.

But is an immune system a factor when it comes to ich attaching to a fishs skin? I'm under the impression that the ich will attach to a fish if it comes in contact. The fish that are infected are the ones who sleep on or near the sand bed.

Clowns are definitely happy and they are hosting in a 12" mag.
