So I woke this morning to find this on my glass. Is it some sort of snail eggs? It's almost at the top of the glass so that's the only thing that I can think of. I zoomed in on the camera and it looks like a couple thousand eggs.
I hung a piece of plexi glass in front of the eggs with a couple of veggie clips to protect them from the fish so we'll see what happens. It would be pretty cool if some survive.
