The black neon tetra is an egg scatterer, laying adhesive (sticky) eggs over plants, etc. One female can produce several hundred eggs. The parents will eat their own eggs and babies, so it is normal to remove the parents after spawning. As with many fish, The black neon tetra often spawns in the early morning. Raising the fry can be more difficult because of their small size. The first food will normally be protozoa (). Very fine fry food can be used, graduating to slightly coarse fry food. At all ages, the black neon tetra benefits from suitably sized live food.
