Description


General: The Dwarf Neon Rainbowfish (Melanotaenia praecox) is an highly adaptable, schooling fish species from the eutrophic (nutrient rich, heavily planted) ponds, and streams of Australia. The Dwarf Neon Rainbow will reach a length of three inches, and live well over five years in captivity. It is critical to maintain schools larger than six, with a 1:2 male to female ratio with the Dwarf Neon Rainbowfish.

Fecundity: The Dwarf Neon Rainbowfish (Melanotaenia praecox) may produce several hundred eggs per clutch. The scientific genus Melanotaenia reproductive behaviors are unique, as all eggs are not laid simultaneously. The female will deposit eggs in numerous passes. It is best to remove the parents, as it is frequently recognized that Rainbowfish do consume their eggs.

Preferred Water Chemistry: Neutral (6.5 to 8.0 pH), intermediate water hardness (6 to 18dGH)

Aquarium Diet (Omnivore): Brine Shrimp, Blackworms, Omnivore Pellet, Spirulina

Dimorphism: The Dwarf Neon Rainbowfish (Melanotaenia praecox) male will have developed a vivid coloration, once mature. The female will retain her more basic coloration. The male will also have a slightly more exaggerated, dorsal arch.

Compatibility: The Dwarf Neon Rainbowfish (Melanotaenia praecox) are typically compatible with Barb, Danio, Hatchetfish, Corydoras, Botia, large Tetra, and other Rainbowfish.
