Many of the invertebrates we house in our aquariums are capable of spawning successfully. Many snails, anemones, and sea stars can propagate very easily. However, most shrimp and crabs release tiny larvae that either get filtered via our equipment or eaten by other fish. If you want to attempt to raise these offspring, you should remove as many larvae as possible and relocate them to another aquarium…preferably one that doesn’t have other livestock in it. The growing larvae will need plenty of food and very stable conditions in order to survive.
