I recently acquired quite a few corydoras pygmaeus from my LFS and was looking into breeding them. Do they require very specific water parameters? My tap water is ph ~7.4

Do you feed them anything special? I have omega one flakes and hikari algae wafers that I crush up and feed but also got frozen and freeze-dried bloodworms.

Have you ever done a big water change(50%) and with water temp a couple degrees cooler than the tank?

I have. Many times. Just did an hour ago as well. They seem happy as usual just no spawning.

I'd drop the temp to about 72/73, keep species only and feed a varied diet.
The thing with corys are they are pretty good at finding their eggs. So you need to learn to recognize spawning behavior.
I need to scan my cory tank about 3 times a day, as I am never sure when they will be busy doing the tango, and being 2 hours late can mean only finding dots on the glass. Despite cover I have only ever found one baby that made it to quite large size in the tank. So, I harvest all eggs and dump them in the same breeding net with the fry. I couldn't possibly feed the parents more.
The little pygmies should spawn about once every 3 weeks to a month, once they are adult. Unless wild harvested anything you get from the LFS will likely still be juvenile, as breeders don't grow fish to adult size.

Possible all but 2 (my oldest surviving members of my first attempt at pygmy) are too young yet, good point.
Also they are not species only they are in a planted community I would call lightly planted at this time as now that I use root tabs and liquid ferts is coming on but is no means a forest yet.
Those two factors probably explain why I have no baby pygmy lol
