Sick fish....QT tanks and the headaches... how do you cope?

[Hustler]

Almost anyone i talk to around here dosnt QT anything.... as most of the stores we frequent have copper tanks ect anyways and will hold fish a while for you as well.
Seeing as everything was healthy and eating prior to adding them i figured i would have the same luck...
And luck is what i chaulk this up to with salt water....LOL
Im not about to tear down my display... Ill deal with the QT and do a dip from now on i guess... but if its stress that causes it then a dip is just increasing the chances...
