Species description

Geographical Origin and Habitat: Western Indian Ocean: coasts of South Africa and adjacent subtropical reefs.

Taxonomy: Belongs to the Alpheidae family. It exhibits a morphology typical of reef-dwelling scavenger invertebrates, growing to a size of 4.0 cm.

Social Behavior: Very peaceful and secretive. It leads a benthic lifestyle, spending much of its time sheltered within crevices or sandy burrows.

Coloration and Sexual Dimorphism: The coloration consists of cryptic or distinct markings helpful for camouflage. Sexual dimorphism is not externally prominent.

Care, breeding and tankmates

Tank Setup: Requires a reef aquarium of at least 80.0 liters with stable rockwork. Provide shaded areas and caves to shelter during molting.

Diet and Feeding: Omnivore. Acts as a scavenger, eating leftover foods, micro-crustaceans, organic debris, and sinking pellets.

Water Quality: Reef parameters with pH 8.1-8.4, gravity 1.023-1.025, and low nitrates are critical.

Compatibility and Tankmates: Peaceful. Reef-safe. Do not house with large, aggressive fish species that might consider it prey.

Aquarium Breeding: Simultaneous hermaphrodite. Breeding is complex due to a prolonged planktonic larval phase which rarely survives.

Risks and Diseases: High sensitivity to copper-based medications. Risk of osmotic shock; requires slow drip acclimation.
