Egg identification

[Madchild57]

Hey all,
I found these eggs in my 55 gallon, there were some on the glass and some on this fake plant. They're like clear flat discs.
The only tank inhabitants able to lay viable eggs are my angel pair, cory cats, and nerite snails. The eggs do not look like angelfish eggs (plus the parents would be guarding them), nor do they look like nerite eggs. It's only about a week and a half removed from when my lone female cory last laid eggs. It seems too early for my cories to lay eggs again.
Other than that, I have 2 female honey gouramis, a female thick lipped gourami, and a female rainbow shark. I'm not sure if any of those can lay eggs without a male.

It's most likely to be the corydoras.

My guess is cories as well

It's most likely to be the corydoras.

alright that's what I was thinking but it seemed so unlikely since they just laid eggs so recently

I've seen weather make a fish spawn again sooner than they should. If you had a cool front, or a storm front move through and drop the barometric pressure by a large amount, it can trigger a fish that's just marginally ready to go again.
