Is this possible?

no cause the fishes immune system fights off the white cysts in a few weeks. it remains in the water so it is possible the fish could keep being reinfected and beating it back in 2 years but the white cysts would not stay on the fish for a full 2 years.
I guess it would be considered dormant ich. Kind of like remission for cancer patients.
Ich is almost like the common cold. You catch a certain strain, your body adapts and eventualy becomes immune. Until next cold/flu season where a new strain is introduced and the infection starts again. Ich can lie dormant as your fish have become immune. Add a new fish who's not immune, they catch it, ich reproduces into yet another new strain and infects the entire tank all over.
At least that's my understanding. That's why quarenteen/hospital tanks are a good thing to have.

"Particularly resistant fishes can remain asymptomatic through several cycles of infestation and can act as "carriers" of Ich. What happens is, the free-swimming tomites attach most easily to the gills. The rest of the fishes' skin is protected by a sturdier mucus coating that's constantly renewed, sloughing off all kinds of minute organisms that might settle out. Trophonts that are newly-attached to the epidermis are invisibly small. So a "carrier" fish is simply one that is invisibly carrying Ich, perhaps on its gills. There is no "dormant" independent, long-term encysted life stage separate from a host fish for Ichthyophthirius multifiliis. This is useful to know. You will often hear to the contrary. Dr. Peter Burgess, who took Ichthyophthirius multifiliis as his Ph.D. subject at Plymouth University, mentioned among Ich "old wives' tales" that "It's present in all aquariums." "What utter rubbish" noted Dr. Burgess (in the November 2001 Practical Fishkeeping). Brits don't mince words."
I'm curious, has anyone had an Ich outbreak in a tank that there is absolutely no possibility of the introduction of Ich from an outside source?
I have heard of people saying that their loaches (in an established tank) came down with Ich after a drastic temperature swing. Has anyone experienced something like this?

What I wonder actually is after a dye or copper based bombing, will there still be ich left?
Twice a week my tank temperature dips from 78 to 72...no ill effects do far for about 6 month(summer doesn't count)...and I have 30 loaches.

You have a great loach collection. I want loaches in my next tank but I can't/won't add anything else until I set up my new tank.
for my first little shoal of loaches. Ich infested and a darn shame..
