How to get Salt n Pepper Corys to breed?

[Potaqua]

Updated,

I kinda of just left the tank to just go wild and green. I add a few frogbit and parameters are good. 

Weeks later, while I was doing fishroom maintenance, out of no where they started to T-shape each other and doing the mating ritual. I was like wth? So water changes didnt work, pH change didn't work, and temperature change didn't work. But just leaving them, doing nothing and letting the tank go wild cause a trigger. Idk what trigger their breeding?

Now im stuck ponding how am I gonna find their eggs in this green water. 🤦‍♂️🤦‍♂️🤦‍♂️😂😂😂

Pull the parents and see if the fry raise up in there, maybe?

IME they parents don’t eat the babies. 

[Potaqua]

I'll pull them out to see if any of the eggs survive.

@Potaqua Keep us updated on the progress. I love corydora babies they are so cute!

Update,

Still no eggs, separate the adults from the tank, but no babies and no eggs. Added them back into the tank.

I have recently try 90% water change with cold water. I check all the added plants in the tank. I didnt see any eggs. Now im doubting that I have a male out of the 7 that I have or im just having bad luck. 🥲😔

But you mentioned they were doing the T shape right?  I could be wrong but I doubt the females would have any instinct to take that posture.

It could be that they're eating their eggs?

I guess I will have to sit and watch them finish. Their tank started to clear up now. I'll also double check the plants too. 🥲 Corys are harder to breed than I thought.

Update

Im gonna try to do 2 male and 1 female in a breeding tank to see if I have better luck.

1 m 1 F has worked best for me, but it does involve A LOT of waiting. 🫠

Update

I sat up all morning watching my Corydoras do their mating dance and T-shapes. 

Lol the males definitely into the mating. They were bugging the fat females, but my female didn't seem to care and didn't lay any eggs. 😂

Update,

I FINALLY HAVE EGGS AND BABIES!

I was doing some spring tank cleaning today and found few eggs on plants. Im pretty confident there are more somewhere in the tank. 

I think the problem was the females weren't mature just yet. The females have double in size since my last update.

That makes sense. Your last pic a few comments ago, the female looks a little small. 
My breeding females are generally quite large compared to the males.

[Potaqua]

Yep!

Weirdly, I don't have to do any cold water changes to trigger them to breed. I give them blood worms or tubular worms and they would spawn the next morning.
