Eggs did come to mind. I’ve got swordtails, cherry barbs, black tetras,, corydoras, bristlenose and a black ghost knife fish

My money would be on cory eggs. They lay eggs anywhere over tank surfaces

I agree. I have had corydoras that lay eggs on the glass like that. They are unlikely to hatch unfortunately as corydoras will not look after their eggs.
