I feel terrible, and want to try to understand what happened so I don't do it again.
Yesterday I got a kole tang, a christmas wrasse and two very small clownfish and put them in a QT I had set up for them. Following the How to Quarantine post the QT tank's water was pre-medicated with Cuprion. I accidentally overshot the ppm - it measured 1.14 when I started. The tank is a 10g with a heater and an Eheim Aquaball. The aquaball has a venturi that produces a lot of microbubbles in tank. I have an ammonia alert badge and a couple PVC fitting in there too.
The fish came from the LFS in three bags. I measured the salinity in one of them at 1.024 and adjusted the QT to match. The tang was in one of the two bags I didn't measure, so it's possible the salinity was different. I floated the 3 bags for 30min unopened, then transferred the fish to the QT (just the fish, not the water). I realized this morning that the water temp was 81.5 - the heater's thermostat turns out to be junk.
When first transferred the tang seemed OK - he was hanging out in some of the PVC and not being very active but didn't seem to be breathing hard of swimming unusually. The wrasse has been hiding in the most sheltered part of the tank and looking stressed, but AFAICT wrasses often "play dead" when they're stressed from tansfer.
My current theories:
* I overshot the initial copper concentration and that was too much of a shock
* Too many fish in the tank for the oxygen available
* The tang's water salinity was lower than what I measured, causing a salinity shock
* The water temperature was too high
* All of the above combined with general stress of QT
