Alpheus cyanoteles

Datasheet

General Description

The Pistol shrimp, scientifically known as Alpheus cyanoteles, belongs to the Alpheoidea family and is characterized by its large claw that produces a distinctive snapping sound, used for stunning prey. Typically reaching a maximum size of 7.0cm, these shrimps are native to regions like the East Indian Ocean, Australia, Indonesia, and the Central/West Pacific. They are known to be peaceful in temperament and are primarily nocturnal creatures.

Aquarium Suitability

Considered suitable for aquariums with a minimum size of 50 liters, Pistol shrimps are labeled as suitable with care due to their feeding habits and symbiotic requirements. They are reef-safe with caution, as they can be a threat to small crustaceans such as shrimp and require specific considerations to thrive in captive environments.

Demands, Care, and Hardiness

Pistol shrimps have average hardiness levels and thrive best in dimly lit aquariums. Ensuring a varied diet for these creatures, including small pieces of seafood and larger frozen food, is crucial for their health and well-being. They prefer water parameters with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature between 22.2-25.6°C.

Reef Suitability

While being labeled as reef-safe with caution, Pistol shrimps must be monitored carefully in reef aquariums due to their potential threat towards small crustaceans like shrimp. However, with proper research and consideration, they can coexist within a reef environment.

Aquarium Setup

To accommodate Pistol shrimps in an aquarium, it is essential to provide a deep sandy substrate for them to create shared caves with their symbiotic partner. Pairing them with species like Amblyeleotris spp., Cryptocentrus spp., or Stonogobiops spp. is recommended for their well-being and natural behavior.

Behaviour

Pistol shrimps exhibit peaceful behavior within aquariums, particularly when paired with suitable symbiotic partners. They are most active during the night, displaying increased activity levels in low-light conditions or darkness, characteristic of their nocturnal nature.

Feeding and Diet

Maintaining a varied diet for Pistol shrimps is essential, including offerings of small crustaceans like krill, mysis, and artemia, along with larger crustaceans and other invertebrates. Regular feeding schedules with appropriate food items contribute to their overall health and vitality.

Habitat and Distribution

Found in regions like the East Indian Ocean, Australia, Indonesia, and various parts of the Pacific, Pistol shrimps inhabit sandy substrates close to coral reefs. Their natural habitat features a symbiotic relationship with specific fish species, creating shared burrows in the sandy ocean floor.
