IMO, if you don't treat new fish prophylactically for ich while in quarantine then your fish are more at risk. With some types of fish (like tetras), you can quarantine them for a few months and never see any signs of ich.
Generations of Ich can stay hidden in the gills for a very long time,while each generation of ich gets stronger and stronger. Some time, like 3 months down the road, an ich strain might finally be able to penetrate the weakest fishes slime coat. If that fish is a loach, it probably won't be seen until it's too late. By then the entire tank may be infested and every fish inside may be fighting for it's life.
Unfortunately I learned this the hard way about 3 years ago. Lost about 30 clowns to ich even after doing standard quarantine treatments. I guess everyones luck varies if they don't treat for ich. Best just to take luck out of the equation.
If you have many fish in your main tank and have made a huge investment in them not just financially, but emotionally, then don't take any risks. The more loaches you have, the more devastating ich can be. Treat the new fish the one time while in quarantine, then you'll never have to worry about ich again.
A prophylactic ich treatment is the only way to guarantee that your main tank will remain ich free.
