all made it, i was extremely surprised. the ich got to the point where you couldn't even see any purple on the PT... i was almost in tears watching them (were several YT's in QT also).
the only bad part was when I finally added them to my 450g DT, the other Tang's went ballistic on the new arrival Tang's... most were cut up pretty bad, and I was yet again pretty sure most of them would die... felt awful. But, a couple days passed by, and even now 3 months later everyone in the tank is swimming around together peacefully. Lots of stress that first month!
