Exclamation Fish die-off after water change/plant moves - anyone ever had this?

So I did a WC on my 36 gallon tank (in sig). About 40% with a water changer - I'm on well water. Before change I was 0/0/20 with no ammonia, after it was 0/0/10 and no ammonia (and no chlorine). Temp of the tank only change by a degree or 2 (78 to 76 or so)

I moved some plants around (some stuff got tall in the front), and trimmed/removed some ratty leaves. Took about 40 minutes total with the filter off.

Immediate loss of the 6 Cardinals I had in there and about 5 chili rasboras. 6 Platy in the tank are hiding, but moveing and fins not clamps. Ottos being thier normal self, Amano shrimp are fine, RCS look ok, Pygy cories hiding to well to tell.

The dead fish seemed to drift in the current like they were in a coma, coming to once in a while and finally having no reponse at all. No sign of disease, they were 100% normal before I started.

What gives? You ever have this before?
