Corydoras pygmaeus colony breeding, surprise!

[Gypsum]

For what it's worth, I've had pygmaeus and habrosus in the same tank for about two years now. The habrosus have spawned. I bought six, lost three in a white spot outbreak, but I now seem to have six again, through zero effort on my part. The pygmaeus have shown spawning behaviour but doesn't look like anything has survived. Recently cleared the tank of the Aspidoras spilotus invasion, distributing the bloody things to the LFS and other tanks, so it's chilled and quiet now. I had over forty. Started with six. If you want a cory species that breeds like rabbits.....
