The Pacific Cleaner Shrimp, Lysmata amboinensis, is a marine invertebrate found in tropical waters. This species is recognized for its striking appearance and unique behavior. Its vibrant colors and graceful movements make it a captivating inhabitant of coral reefs. It plays a role in its ecosystem, interacting with other marine creatures.
Appearance and Natural Habitat
The Pacific Cleaner Shrimp features prominent red and white longitudinal stripes along its translucent body. Its slender form can reach approximately 2.4 inches (6 centimeters), with long, delicate white antennae often twice its body length. These antennae are constantly in motion, acting as sensory organs to detect surroundings and potential clients.
This species is native to the Indo-Pacific region, spanning from the Red Sea to French Polynesia. They inhabit coral reefs and rocky crevices at depths ranging from 3 to 100 feet (1 to 30 meters). They establish cleaning stations on prominent coral heads or rock formations, where they can be easily spotted by fish seeking their services. Their sheltered dwelling spots offer protection from predators while still providing access to their clientele.
The Cleaning Service
The Pacific Cleaner Shrimp is known for its symbiotic relationship with various marine animals, including fish, moray eels, and sea turtles. These shrimp perform a specialized cleaning service, removing external parasites, dead tissue, and food remnants from their “clients.” To attract attention, the shrimp performs a rhythmic swaying or “dance,” signaling its availability to passing fish.
Once a client approaches, the shrimp carefully inspects its body, even entering the mouth and gill chambers of larger fish without being harmed. The shrimp’s delicate claws are adept at picking off unwanted organisms, benefiting the host by improving its health and reducing disease. In return, the shrimp receives a consistent food source. This interaction contributes to the overall health of coral reef communities by controlling parasite populations.
Keeping Pacific Cleaner Shrimp in Aquariums
Pacific Cleaner Shrimp are popular additions to home aquariums due to their attractive appearance and beneficial cleaning habits. A minimum tank size of 10 gallons is suitable for a single shrimp, though larger tanks are preferable for stability. Maintaining stable water parameters is important, with salinity levels around 1.023-1.025 specific gravity, temperatures between 72-78°F (22-26°C), and a pH range of 8.1-8.4.
These shrimp are peaceful and can coexist with other reef-safe tank inhabitants. They consume uneaten food particles and detritus, contributing to the overall cleanliness of the aquarium. While they may attempt to clean tankmates, not all fish will readily accept their services in a captive environment. Providing plenty of live rock with crevices offers suitable hiding spots, which helps them feel secure in their new surroundings.
