What are these eggs on the glass?

While setting up my 5g, I discovered this patch of eggs on the back of my 20g. I was busy all morning and just now noticed them. Inhabitants: Pristella tetras, bronze cories, endlers, mystery snails, and ramshorns that are newly hatched. I can confidently rule out the snails. So... cories or tetras?

This is the kind of thing that might put me over the edge

Cories stick their eggs to things so they get my guess.
Your fish seem pretty happy~!

Interesting! Cories were the last fish that I would suspect! How did they manage to hang on the glass long enough to lay the eggs? Yeah, I'm beginning to think there's a fertility god lurking around the premises. Glad they're all happy enough to reproduce.

Well, the cories have pretty much eaten all the eggs, so I guess it is no longer an issue. This will be good to know for future though.

OK, found a good video on hatching cory eggs. He used a credit card to scrape them off. There were a few eggs still on the glass, so I decided to try it. Unfortunately, the eggs all rolled off the credit card and onto the substrate, where the cories gobbled them up within seconds.

If it happens again and I'm better prepared, I'll try to hatch them.
