The easist way to get seasonal Amazon basin breeders to spawn is simiple:

Put them in the proper tank.

Condition them well.

Do a 25-50% water change with water that is both cooler (10 degrees or so) and softer than the existing tank water.

Spawning usually takes place within 24 hours.

What you are doing is simulating the onset of the rainy season, which creates an infusoria bloom as the rivers rise and flood more of the land. So when the eggs hatch, there will be sufficient food to ensure the fry a chance to grow up.
