Are these eggs?

I found these stuck to the glass of my aquarium tonight. They really look like eggs, but I don't know whose eggs they would be if they are. Right now in the tank I have 9 zebra danios, 2 boesemani rainbows (male and female but very young), 5 albino cories, and a gold nugget pleco that was just added this afternoon. Everything in the tank is very young except for 3 of the zebra danios and the cories which were originally in my 20g tank. Do you think these could be eggs? I'm attaching a picture. It's pretty bad, but the best I could do. They really look like small round brownish dots stuck to the glass. There are also a few on another wall. Some are white, but I assume those would probably be dead.

If anything, I think it's cories. They do lay eggs on the glass, where the other fish don't.

Are they ball-shaped, or more flattened/dome-shaped?

Well they are round, but since they are against the glass one side appears a little fat on some of them.
