Treatment partially depends upon the fish in the aquarium. Some handle medications better than other species which find them highly stressful. Also, the best cure is prevention. Maintain good water quality, weekly partial water changes, live plants help with this too, don't overfeed, don't overcrowd--and very importantly, keep compatible species to avoid stress. Ich always, and I repeat always, occurs due to stress.
Compatible means the fish in the aquarium have common requirements respecting water parameters, decor, and have compatible behaviours. A happy fish is a healthy fish.
Most of us see ich notwithstanding all the above. But if the aquarium is built around the above principles, fish can fight it off to some degree. But if it becomes more than they can handle, treatment depends upon the species' tolerance of medications and heat.
