I'm surprised the eggs haven't been eaten already.
All of the characin fish in the photo are egg scatterers, meaning the female with a male will enter a thicket of plants and the eggs are expelled into the water as the pair hover side by side; the eggs are sticky so they tend to adhere to the plants. Usually, the other fish in the tank know what is going on, and will be waiting to gobble them up.
The only way to save the eggs and fry is to remove them. This can be to another small tank, or into one of those mesh breeding nets that can hang in the main tank at one end. Water has to circulate around the eggs or they may fungus, and the mesh net will provide this.
