Common name: Stimpson's Pistol Shrimp
General information
Stimpson's Pistol Shrimp, Synalpheus stimpsonii, is a fascinating species known for its asymmetrical claws, with one being significantly larger than the other. This larger claw can produce a loud snapping sound used for communication and defense. These shrimps are relatively small, usually not exceeding 2 inches in length, and exhibit a range of colors from translucent to shades of yellow, brown, and red.

Care
In the aquarium, Synalpheus stimpsonii requires a setup with plenty of live rock and a sandy substrate to mimic their natural environment. They are generally peaceful but can be territorial with conspecifics. It's important to provide hiding places and a stable environment with consistent water parameters.
Reproduction
Pistol shrimps are known to form monogamous pairs and engage in complex mating rituals. They typically breed in the safety of their burrows, and the female carries the eggs until they hatch into free-swimming larvae.
Symbiosis
Some species of pistol shrimp, including Synalpheus stimpsonii, engage in symbiotic relationships with gobies, particularly those in the genus Amblyeleotris or Cryptocentrus. The shrimp maintains a burrow that both the shrimp and the goby inhabit. The goby acts as a lookout while the shrimp works on the burrow. This relationship provides the shrimp with protection, while the goby gains a safe home.
Habitat
Synalpheus stimpsonii is typically found in shallow tropical marine environments, often in coral reefs or associated with rubble zones. They are distributed across the Indo-Pacific region.
