Letting the tank sit..

[fmelindy]

I think if it were me (and it has been me before!) I would get that firefish out (donor? sale? QT?) and wait 2 months before putting any more fish in. Assume that firefish does have ick and don't rely on what it looks like. That 2 months will be enough for you to take a break and discover what I think most reefers will at some point realize - there is no possibility of NOT having a tank. (at least there wasn't for me) If you get out of the hobby and sell everything I can pretty much guarantee you next year you'll have another one set up and in the mean time you will have lost your shirt on the stuff you sold. (again, just based on my own experience)

then after your 2 month break, QT everything so you don't go through this again. and keep your shin up, man, this kind of thing has happened to me A LOT. But I keep coming back to the hobby and I learn something every time.
