[edit] Overview

Mysid shrimp are often abundant in a reef aquarium or refugium, although it takes a sharp eye to see them. Mysids make excellent food for small fishes; if they are in a refugium with access to the main tank, enough escapees make it into the tank to provide supplemental nutrition between scheduled feedings. They most often enter the aquarium with algae, such as Chaeto­morpha, which forms dense mats of wirelike strands within which the mysids may be protected from predation.

Family: Mysidae

Other common name(s):

  • Mysid Shrimps

Native range:

Maximum length: 30 cm (12 in)

Minimum aquarium size: 38 L (10 gal)

Lighting: Immaterial.

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

[edit] Feeding

They may be fed using phytoplankton.

[edit] Aquarium Compatibility

Highly desirable as a self-replenishing live food source in reef aquariums.

[edit] Special Care

Because they feed on microalgae, their refugium needs enough light to allow algae to thrive.

[edit] Notes

Distantly related to true shrimps, mysids have a decidedly shrimplike shape and are largely transparent. They lack the thoracic walking legs seen in most shrimps and instead have slender paddlelike appendages.
