The yolky eggs undergo direct development without the presence of a true larval stage. The eggs are laid in large colorless capsules during the night. The swollen capsules shrink as the embryos develop and, after approximately thirty days of embryonic development, the young hatch, resembling miniature adults, about 5 to 7mm in length. The young maintain a vertical body structure for a period of time, floating and drifting submissively through the water. Growth occurs rapidly for the young during the summer, and the species is sexually mature between the months of June and October. After 1 to 1.5 years, the adults die, completing the life cycle.
