OP has not yet posted water results.
It was my comment about pH on my tanks and how some of my cories have reacted in a somewhat similar way to what OP is experiencing after big water changes, which I've now stopped (reduced the volume) because by chance I found that my tap water is literally -and suddenly - off the charts alkaline
