37G FW - 3 Pearl Gourami, 4 Black Mollies, approximately 20+ Molly Fry, 5 Assassin Snails | 10G Planted FW - 14 Molly Fry, rocks, DW and an Anubias Nana - journal

Most of this is from what I've seen and read myself, it may not be true for ALL cory species but its true for several at least. (I found the way they breed to be kind of fascinating so I read up a bit more):
So your "rainy season" either real or replicated in aquarium happens and both fish (male and female) realize its time to create young.
The female starts producing eggs and getting fatter. The male starts showing off for his lady to show he is a good match, with wiggling and dancing and encouraging her to take things to the next step.
The female engages the male in a breeding T shape position. At this point she takes the sperm from the male through her mouth and directs it to where she is holding the eggs within her body. This fertilizes the eggs.
She then finds a location she thinks is suitable and begins to lay the now fertilized eggs.
I did find the start of this video to have a good visual on the T-position (this is not my video, its just a decent illustration):
As for witnessed in my own tanks.. I've seen the showing off and the egg laying from my pygmys (basically you see these itty bitty drops come out of the underbelly of the cory and she rubs them off on leaves) and I have seen the scatter of a few of my panda cory eggs.

Personally my corys lay all the eggs on the glass, but if you have snails in the tank its a free snack time
I also believe some external weather may effect it with the barometric pressure etc - just from what I've noticed that there are times you repeat something but it doesn't work, only difference is time of yr or weather
