And I don't buy the theory that a fish can have immune to ich. Ich is not a virus or bacteria. it's a parasite and it can attach to anything it get in contact with.

A healthy fish has a slim coat over its scales and in its gills. Which keeps ich from attaching itself.
Stressed fish lose the slim coat and are more Likely to be effected by ich
