Kole and Naso QT Help

[Camps23]

Hey all,
I went to have a peak at a yellow eyed kole tang (3.5") today and confirmed he was fat and healthy. I setup my 15G QT tank before I left. I will be picking him up next week as I will be out of town for the next few days. Problem is I fell in love with a blonde naso tang (2.5") while i was there as well. Im in the process of upgrading from my current 75G to a custom miracles 145G. I was going to QT the tang for 3/4 wks(new tank will be plumbed in the next few weeks). I know the naso will out grow my tank but I have plenty of friends with large tanks that will be happy to take him as soon as I notice stress or aggression. My problem is how can I QT both of these guys ? Will they both be ok in a 15G QT tank ? Do you guys normally treat a fish with medication even if there is no sign of illness ? What medicine if so ?
Thanks

I would not put both of those guys in a 15 gallon for any extended period.

Is my only option separate QT tanks ?

You never want to QT multiple fish in a single tank. The purpose of a quarantine is to watch for disease. What do you do if one develops infection? Treat both?

So if i QT just one at a time do I treat no matter what or do I only treat if I notice a parasite

That's a hotly debated topic. One school of thought is to treat with copper. The other is not to treat unless a parasitic disease is detected. With tangs I'd lean towards treating... but that's just my opinion.

I hypo everything, symptoms or not. After putting all of my fish thru hypo and leaving my DT empty for 8 weeks, I put a flame angel in QT for 6 weeks. Angel looked perfect the entire time, did not treat. Within one day of being placed in the DT, he had spots all over him. I'm sure he was stressed being introduced to the other fish. He only had spots for a few hours, cleared up and looked perfect but with the next addition to the tank (after QT also) the ick was back with a vengence! Never again, everything gets treated, it is not worth risking the health of all of your other fish. Also I had to start all over with hypo and a fallow tank--not fun!

Can someone provide a link on the proper steps to treat with hypo salinity in a QT tank
Thanks

I think the lowest you start is 1.018 or 1.019.
