Thank you for the info. What appears to be small white lines are actually the bubbles and debris moving from the filter that is directly behind the eggs. I did a 75% water change and gravel cleaning 3 weeks ago, I have had at least 2 to 3 fry from each batch my Cory's laid, and for the last year it has been one batch a week, I have more than one pair of cory's that love to lay eggs. I am not trying to bread them, they do this on their own and I leave them alone. I am just amazed that they lay that many eggs as often as they do. Especially when the temp in the tank is not set for them breed, it is set for my rams to breed to which is about 6 to 8 degrees higher than what the cory's are said to breed in.
