They don't look fertilized to me. By now any fertilized eggs should be brown or tan indicating that there are growing fry in them.Thanks guys!! If they are Cory eggs what are the chances they will hatch?? And do I need to do anything to keep the other fish away. They have decreased in numbers this morning but the ones that are gone were the ones you could see through. I see about 13 this morning. Oh and I forgot..there is 1 Otto in the tank also.
