I usually QT all new arrivals for at least 4 weeks, with the only exception being a moray eel that I QT'ed for 10 days. I currently have a hippo tang that I purchased 12 days ago from a LFS. I was planning on QT'ing this particular fish for 4 weeks at a minumum- do to their reputation of being ich prone. I need to leave town this weekend for a three full days to attend a family members funeral, I leave early Thursdays and will arrive back the afternoon of Monday. I can't locate someone to watch my tank on short notice. I have never had a fish come down with ich, but I'm wondering if ich will usually show up within the first week or two of being QT'ed? I really don't think I should leave the fish in the QT tank for a couple of days without watching, but my main display is 215G with plenty of algae and stuff for him two pick on for a couple of days. I would like to add him to my main display tommorow, and that will give me 48hrs to watch him for any signs of trouble with the other fish before I leave town. I really hate this, but I'm not sure of my best choice. The tang is looking really good and is quite healthy- should I be ok with just the two weeks of QT? Appreciate any input.
