I wouldn't treat a fish for ich unless it was the last straw and the fish was declining fast, not eating and such. Treatment and QT can add unnecessary stress and make the ich worse, I would let the fish try and beat it on its own till it stops eating. If it stops eating you must treat the fish. I find that if you do a water change and improve your water quality it improves the fishes chances of beating it on its own. This whole thing about treating the whole tank because it will spread is nonsense. If it spreads its only due to other factors like weak fish due to stress and poor water quality. If you have good water quality and healthy fish it wont spread.
