I setup a 20g QT tank a couple weeks ago and moved my 4" yellow tang and 4 other small fish into it last week. One fish, the flame angel, was badly covered with ich. and I knew she would die before I even moved her, and in 2 days she was gone. The rest of the fish were very healthy, one or two had a spot of ich, that's all. My yellow tang never showed any spots.
The QT tank itself is cycled, I used a filter pad from another tank, and aside from a 24hr ammonia spike of 1.0 last week, there are zero ammo and nitrites.
I put the fish in QT (I'd filled it with display tank water), waited 72 hrs, then did four 5g water changes over four nights to drop the salinity to 1.009. The drop was something like 1.023 -> 1.019 -> 1.015 -> 1.012 -> 1.009. When I did the changes, I dripped the new water in over 3 hours, so it was a nice slow change. They've been at 1.009 for 48hrs.
The tang has been breathing heavy for days, mainly sits on the bottom, rarely moves about much, and hasn't eaten in 5 days or so. Tonight he seems to be starting to tilt sideways.
The only area I can think of where I may have been careless was with pH. I think the pH got up quite high - 8.8 - when doing the drop to hypo, and was there for a couple days. Yesterday it was around 8.5, and I used a teaspoon of vinegar to drop it to about 8.3, which is where it remains now.
Does this sound like something that could have harmed the tang? The tang is very plump and used to eat ravenously, compared to when I first got her, she was emaciated.
I've rechecked all water parameters tonight:
pH - 8.3
salinity - 1.009
ammo - 0
nitrite - 0
temp - 80
Anyone have any diagnosis or ideas?
