Common name: An opossum shrimp

General information

The Common Opossum Shrimp, Neomysis integer, is a species of mysid shrimp found in brackish and coastal marine waters. These small crustaceans are an important part of the aquatic food web, serving as prey for a variety of fish species. They are characterized by their transparent bodies and the presence of a marsupium, or brood pouch, where females carry their eggs.

Care

While not commonly kept in home aquariums, Neomysis integer can be an interesting addition to a brackish or marine setup that aims to replicate a natural ecosystem. They require stable water conditions and benefit from the presence of fine particulate organic matter, which they filter from the water column. A gentle current and plenty of hiding spaces are also beneficial.

Reproduction

Neomysis integer reproduces sexually with females carrying the fertilized eggs in their brood pouch until they hatch. The larvae go through several developmental stages before reaching adulthood. In an aquarium setting, breeding Neomysis integer can provide a live food source for other inhabitants, particularly larval fish.

Habitat

Common Opossum Shrimp are typically found in estuaries, coastal areas, and sometimes in freshwater environments. They are adaptable and can be found at various depths, often forming swarms in areas with high organic content.
