Species description
Geographical Origin and Habitat: Native to the Caribbean Sea and western tropical Atlantic, living in symbiosis with sea anemones on shallow reefs.
Taxonomy: Classified under the Palaemonidae family. It features an almost completely transparent body with purple and white spots.
Social Behavior: Peaceful and symbiotic. It establishes cleaning stations on host anemones and sways its body to attract fish for parasite removal.
Coloration and Sexual Dimorphism: Glass-like transparency with purple spots on the legs and tail. Females are larger than males when mature.
Care, breeding and tankmates
Tank Setup: Needs a reef aquarium of at least 10 gallons with a healthy host anemone (like *Condylactis gigantea*) and stable rockwork.
Diet and Feeding: Primarily feeds on fish parasites and mucus. Also accepts fine frozen foods, dissolved organic particles, and micro-pellets.
Water Quality: Requires stable marine water: pH 8.1-8.4, temperature 22-27°C, salinity 1.023-1.025, and zero copper concentration.
Compatibility and Tankmates: Safe with corals. Avoid predatory tankmates like wrasses, hawkfish, and large crabs that can easily prey on them.
Aquarium Breeding: Spawns in captivity, with females carrying egg masses under their tails. Raising the larval stage is extremely difficult.
Risks and Diseases: Prone to predation if forced to leave the host anemone. Highly sensitive to osmotic shock during water changes.

- Calcium and minerals
- Richiede calcio e magnesio per la solidificazione del guscio.
- Molting
- Muta regolarmente all'interno dei tentacoli dell'anemone ospite per evitare i predatori.
- Reproduction
- La riproduzione non ha successo in acquario domestico a causa dello stadio larvale fluttuante.
- Compatibility & tankmates
- Convive in simbiosi con anemoni (es. Condylactis gigantea). Non compatibile con grandi pesci carnivori.
