Neon Dwarf Rainbowfish are egg layers, and will scatter their eggs among broad leaf plants and foliage. Fry can be difficult to raise. Males are larger and brighter than females. Males will fight during spawning (which happens in the early morning) often encircling and nipping one another, along with a display by extending their fins and increasing their intensity of iridescence. Females will then spawn continuously for several days whilst the male fertilises the eggs. Fry will typically hatch within a week.

Life Span
Neon Dwarf Rainbowfish can live to anything from 3-5 years in perfect conditions.
