Can Skunk Cleaner Shrimp (Invertabrets) Get ICH?

I was just wondering becuase I have totally avoided ICH and fish disease for almost 2 years but I just bought a cleaner shrimp today and I looked at him hard when I released him into my aquarium and I noticed white sports on him. I am not sure if it is sand particles or disease.
Any suggestions?
I use 'Prevent ICH' and it works. I put the requested amount of solution in my tank prior to his release.
Thanks
