My aquarium only 1 has common goldfish which isn't really that old, I installed a new light today and noticed a few smallish white eggs around 1mm in size dotted around the tank. Some inside my driftwood, and a few stuck on the window. I soaked the driftwood for a week then added it to my tank about a week ago, but have only just noticed the eggs.
Congrats, seems like you have a girl. She probably squirted those eggs out a few days ago. They turn white after a few days if they aren't fertilized. You should remove them or they will begin to grow mold/fungus and foul your water.
