thanks! Great to hear some personal experience. It is hard to come by for these fish. I am QT'ing a two-spot bristletooth right now. I'm doing copper and prazipro. Definitely not taking chances because I know these guys are delicate. Any idea why yours died eventually? Did they seem skinny, stressed out, diseased, or anything towards the end? And, any tips of what prepared foods they will accept at first? anything besides the obvious like nori, formula II, etc...
