Next time they spawn get a razor blade and at a 45* angle or less gently scrape the eggs off the glass and stick them to the side of a 10g tank and treat with methylene blue and set air stones under the eggs so there is good water movement over the eggs. Some eggs will fall off the glass but that's fine, the fresher you get them the better they stick. I tend to get them as soon as I can, some times while they are still doing their thing. You will need to have a sponge filter in the tank, of a HOB with a sponge on the intake tube. Run some carbon as soon as the hatch and fall off the glass. It will be a few more days before they use up all of their egg sack. Once the egg sack is gone then you can feed with well softened shrimp pellets or whatever you are feeding the adults. The eggs will normally hatch after three days and the fry will feed from their yolk sac during the initial 48 hours. Microworms and liquid egglayer fry food are suitable as first foods. When the fry are around two weeks of age, you can start feeding the crushed flake food and brine shrimps.
