The eggs are small in size, from 0.9 to 1.0 mm, and can withstand much abuse. The eggs are a little bit adhesive and can be seen in a peat moss with some effort. Please note that the eggs incubation period of Argolebias nigripinnis can be as long as 3 - 4 months and even longer, depending on the incubating temperature, peat moisture, and other factors. You have to be quite patient checking the eggs every 3 - 4 weeks for the embryo development.

Hatching can usually be induced by simply placing the eggs in shallow water in the raising aquarium (container) after 3 - 4 months of incubation, where the wetting of the eggs stimulates hatching. Do not be tempted to hatch the eggs early, as this can impair the development of the fry. If the eggs fail to hatch, place the substrate back into storage for another 2 - 3 weeks. Repeat this until you get a hatch. Some breeders even re-dry the peat following a hatch and wet it again after another 4 – 5 weeks. This often yields more eggs that have developed more slowly. Eyed-up eggs with moving embryos inside are a sure indication that the eggs are fully developed. When you hatch the eggs do frequent water changes for increased fry growth rates. The fry are medium in size and can be fed with BBS or Microworms at birth. If you maintain the water as recommended and diversify fry's food, they can be sexed out in about 4 to 5 weeks, and ready to breed at 5 - 7 weeks. This species can be easily bred and maintained as long as you act in accordance with all the recommendations.
