Common Names: Peppermint shrimp, Candy Cane shrimp, Caribbean cleaner shrimp.
-
Size: Small, reaching about 5.0 to 6.5 cm (2 to 2.5 inches) in length.
-
Appearance: Translucent bodies adorned with a network of vibrant, bright red and pink longitudinal/vertical stripes (resembling a peppermint candy) and long, white antennae. Eggs are distinctly bright green.
-
Habitat: Native to the Western Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico; they thrive around coral reefs and rocky areas.
-
Diet & Behavior: They are peaceful, bottom-dwelling scavengers that eat detritus, uneaten food, and are primarily known for eating the pest anemone Aiptasia.
Peppermint Shrimp (Lysmata wurdemanni) are small, peaceful saltwater crustaceans native to the Western Atlantic and Caribbean. They are highly prized in the marine aquarium hobby for their striking candy-cane-like appearance and their natural ability to prey on pest glass anemones (Aiptasia).
Physical Characteristics
-
Size: Reaches a maximum length of about 5.0 to 6.5 cm (2 to 2.5 inches) as adults.
-
Coloration: Their bodies are mostly see-through/translucent, beautifully accented with vivid red and pink stripes spanning the length and sides of the shrimp
-
Eggs: Females carry distinctively bright green eggs.
Behavior & Habitat
-
Habitat: These invertebrates reside in coastal waters, often sheltering in the crevices of coral reefs and among submerged marine vegetation.
-
Diet: As scavengers, they consume decomposing organic matter, uneaten fish food, and nuisance Aiptasia anemones.
-
Temperament: They are highly social, aggregate-living shrimp. However, they are naturally skittish and require ample hiding spots in captivity to feel secure.
-
Reproduction: They are simultaneous hermaphrodites, meaning adults can reproduce as both male and female, though they cannot self-fertilize.
Aquarium Care
In the marine aquarium trade, L. wurdemanni serves as an important member of the clean-up crew. While traditionally sold as a single species, taxonomic revisions reveal that what is sold as the "Peppermint Shrimp" often includes closely related species (like Lysmata boggessi), all of which exhibit very similar appearances and anemone-eating behaviors.
