If you want to try to help any survive. Take a plant or ornament they are attached too and put them into separate tank/bucket/bowl and place some tank water from the main tank in it to about 6inches high. The babies survive on there egg sac until they become free swimming then you want to feed them every 3-4hours. You can buy fishfry food from the lfs as well as freshly hatched brimeshrimp eggs. If you have none of this then boil an egg mix the Yoke only with some tank water to make a protein rich baby food.
