What Fish Eggs Are These

I have gouramis, angelfish, swordtails,gbr, and zebra danios what fish could have laid these eggs?

 

And Cory cats which I believe to be the ones that laid the eggs

 

It will not be the gourami (bubble nest builders), angel or GBR (both are protective of the spawn). I also doubt it was the corys, they stick them to something and do not scatter them. Won't be swords as they are live bearers. That leaves the danios.

 

They look to me like fungused food pellets.

 

I bred angelfish and that's definitely not their egss. They stick on the flat vertical leaf and the parents will guard them untill it gets big. Maybe it's something else ?

 

Yep, that's not fish eggs. That's rotten fungusy food.
