If they are attached to a solid surface, they are cory eggs.

Depends on the species. Bronze(green) cories lay a lot of eggs. My first batch I had 237 eggs, only two females in the tank, and must have had around the same amount this time, again, only two females in the tank, probably all came from the one female, since only one was huge and looked full of eggs. Bronzes lay a lot of eggsI looked online and 1 female lays bout 15 I have a lot more then that
