I'm just going off what I have read from internet articles authored by aquatic veterinarians. Strange that a lot of times people with ich or brook in their tanks will lose all fish except one or two that never develop the disease? That was my situation with brook. 2 wrasses never got it. Natural immunity? Just lucky? PaulB intentionally introduces ich fish into his tank in order to develop and maintain immunity for his inhabitants. So, I guess fish immunity to parasite like ich can be increased with specific methods huh?I don't see clowns being any more resistant to ich than most other fish. Some tangs will show it first, but clownfish are by no way immune. Plus clowns get Brooklynella, so that makes things worse - since the treatments are different and the fish can get them at the same time.
What you may be referring to is tank raised clowns, going from a breeder straight to a hobbyist, without getting mixed in with wild caught fish, almost never show with ich because the breeders do not have that parasite in their systems.
