QT fish from a 180 into a 35?

[falco]

Ok, I knew ich was in my tank but I've been feeding garlic, vita chem, and selcon with all feedings, along with having 3 cleaner shrimp I have seemed to keep it under control. About a week ago I added a purple tang to my main tank and now he is covered with ich. I know to get rid of ich I must keep the tank fallow for 8 weeks, but I only have a 35gal wich would house all of my fish from my 180 gal. I think this would cause more stress, agression and tension, then help. This is my fish list.
1 sailfin tang
1 magnificent foxface
1 blue throat trigger
1 purple tang
1 diamond goby
1 purple firefish
1 pink dottyback
2 true percs
1 neon goby

Should I just qt the purple tang or should I qt everyone in the 35?

Thanks,
Jack

Well Jack,, what's your goal there?

If you want to be finally rid of this parasite, you have to remove and treat all the fish. The diamond goby, purple firefish, pink dottyback, 2 true percs, and neon goby can be housed together in the 35, but you will need something larger for the other fish. Depending on their size, a 55 or 75 gallon tank would be my preference. Also, don't overlook having a cycled, biological filter, otherwise you will kill the fish from ammonia poisoning.
