I QT'd every fish that went into my DT. 2 Prazi treatments and copper for 6 weeks. I added a Mandarin directly into DT and it along with many of my other fish broke out with ich. I will never add one again without putting it through QT. I would do tank transfer and then a couple of rounds of Prazi. I'd set up a temporary pod breeding tank(s) to keep it fed through the process and try to get it on frozen as well.
