After a few days the eggs will hatch and become wigglers. This is when the fish have hatched out of their eggs, but are still attached to the spawning surface, and feeding off of their yolk sacs, which are attached to their stomachs. After five to seven days of being wigglers, the fish have almost completely consumed their yolk sacs and become free swimming. They are very small, but can normally eat newborn brine shrimp as a first food. They can also be fed liquid fry food, which is available at most fish or pet stores.
