I am on my 6th batch of Albino Cory Cat eggs. The first few I got nothing to hatch, then I got one to hatch and it disappeared. I finally got one to hatch and I put it in another small tank and now its back with parents and almost 1" long.
I also have 5 babies that hatched from eggs I just dropped into the smaller tank, they are doing really well. almost 3/4" long now and I just dropped more eggs into the tank, I have seen a very small baby that hatched from that batch too..
I collect the eggs into a small cup and move water and eggs to the other tank,
Good luck,
