When I read your writeup I did think about the fact that the PWC
water must've been a pretty high salinity to jump you from 1.025 to 1.027 with just a 10% water change. I mean really high. That sudden of a salinity increase - as well as that quick of a reduction - could be causing some stress.
It's a good habit to get into to check the salinity of the water in your PWC
bucket before adding it to the tank. It's just too easy to lose track of how many "scoops" of salt went in sometimes, and a simple check can really save your bacon at times.
For now, I'd just keep the water parameters as stable as possible and let the fish recover.
