I think I know what happened.
Last night (the day of the water change) there were at least 12 fry laying on the bottom, stuck to the filter intake, or swimming all squirrely.
This morning I find 2 dead fish, and the remainder all back to normal.
I'm guessing I over fed them to which they ate until sick. Fortunately, the food passed and they recovered; which is amazing seeing how distressed some of the were.
