Uncounted eggs of Hypsolebias picturatus «Volta das Pedras» in the spawning substrate. It's a result of 2-pair x 10-day spawn. 

The eggs of Hypsolebias picturatus are quite small and robust, but can be a bit sticky in their spawning substrate. This species has an extended incubation period, ranging from five to eight months or even more - this depends on conditions such as temperature and moisture. It is recommended to check for embryo development every three to four weeks; though it requires patience, doing so can help ensure a successful spawn.

Incubation of the eggs may take from 5 to 8 months and hatching can be hastened by putting them in a shallow tank of water. However, do not be tempted to rush the process as this might harm the fry. If the eggs still haven’t hatched after another 4 to 5 weeks, repeat this process until they do. Some breeders have even been known to dry and re-wet the substrate, which has led to more varied hatchings with faster development times. When you can see moving embryos within the eyes of the egg then the eggs are ready for hatching. Change out water regularly post-hatch in order to speed up growth rate, and feed Paramecium for first 3 - 4 days followed by Baby Brine Shrimp, Vinegar Eels, Banana Worms or Microworms. Stick to all these steps and you'll find that breeding and keeping this species is quite a simple task - with maturity being attained within 8 or 9 weeks.
