Species description

Geographical Origin and Habitat: Native to the Caribbean Sea and western Atlantic, typically found living on or near large anemones in shallow reefs.

Taxonomy: Classified under the Palaemonidae family. It features a transparent body with long, banded antennae used to signal fish.

Social Behavior: Peaceful and symbiotic. Acts as a facultative cleaner shrimp, waving its antennae to invite reef fish to be cleaned of parasites.

Coloration and Sexual Dimorphism: Glass-like body with distinct purple and white saddle markings. Females are generally larger and carry egg masses.

Care, breeding and tankmates

Tank Setup: Best suited for a reef aquarium of at least 10 gallons with a host anemone (such as *Condylactis gigantea*) and live rock crevices.

Diet and Feeding: Omnivorous scavenger. It eats particles of frozen foods, detritus, and anemone mucus. Supplement with fine frozen foods like daphnia.

Water Quality: Requires clean marine water: pH 8.1-8.4, temperature 22-27°C, salinity 1.023-1.025, and zero tolerance for copper medications.

Compatibility and Tankmates: Safe with corals. Do not mix with predatory species like hawkfish, dottybacks, or large wrasses that will prey on small shrimp.

Aquarium Breeding: Spawning occurs in captivity, with the female carrying eggs on her pleopods. The planktonic larvae rarely survive past a few days.

Risks and Diseases: High mortality risk if not properly acclimated. Prone to predation if the host anemone is not healthy or disappears from the tank.

Calcium and minerals
Richiede calcio e magnesio per ripristinare la rigidità della corazza.
Molting
Esegue la muta all'interno dell'anemone per proteggersi dai predatori.
Reproduction
La riproduzione in acquario non ha successo per la mancanza di nutrimento adatto alle larve.
Compatibility & tankmates
Convive in simbiosi con anemoni (es. Condylactis gigantea). Non compatibile con grandi pesci carnivori.
