Sea Monkey eggs have a very long shelf life. The eggs are dormant, and when kept in the right conditions, they can last for several years.
It is best to store the eggs in a cool, dry place away from direct sunlight to ensure they remain viable. It is also important to add a few drops of Sea Monkey Special Sea-Monkey Food every three weeks to keep the eggs viable for hatching. In this way, Sea Monkey eggs can last for years.
