Overview: Alpheus spp., commonly referred to as snapping shrimp, are a genus of small, active crustaceans known for their distinctive snapping claw used to stun prey and communicate. They are popular in marine aquariums for their interesting behaviour and contribution to the ecosystem.
Care Level: Moderate. These shrimps require stable water parameters and a well-established tank with plenty of hiding places.
Feeding: Omnivorous scavengers. They will accept a variety of foods including finely chopped meaty foods, frozen preparations such as mysis and brine shrimp, and high-quality pellet or flake foods. Supplementing with detritus and biofilm in the aquarium is beneficial.
Compatibility: Generally peaceful but can be territorial towards conspecifics or similar species. Best kept singly or in mated pairs unless the tank is large with ample hiding spaces. Compatible with most reef-safe fish and invertebrates.
Reef Safety: Yes. Alpheus spp. are considered reef safe as they do not harm corals or sessile invertebrates. However, they may prey on small or slow-moving invertebrates such as ornamental shrimps or small snails.
Tank Requirements: A minimum tank size of 60 litres is recommended to provide sufficient space and stable water conditions. Provide plenty of live rock and crevices for shelter and territory establishment.
Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity 1.023-1.025 SG, pH 8.1-8.4, and moderate water flow.
Placement: Place in areas with ample rockwork and hiding spots. They are often found burrowing or sheltering within rock crevices.
Origin: Various species within the Alpheus genus are distributed widely in tropical and subtropical marine environments. Exact origin varies by species and is not provided.
Maximum Size: Typically up to 5-7 cm depending on species.
