Lysmata amboinensis
Reef-safe cleaner shrimp that helps tidy your tank and adds constant activity.
Maintain these water conditions for optimal health and vibrant colors
Lysmata amboinensis, commonly known as the Cleaner Shrimp or Scarlet Skunk Cleaner Shrimp, is one of the most popular marine invertebrates for reef aquariums. At 3–5 cm, these juveniles are already active, hardy for a marine shrimp, and full of character. Their bright red-and-white markings, long white antennae and constant “dancing” behaviour make them a standout addition to any saltwater setup.
Cleaner shrimp are best known for their natural cleaning behaviour. In the wild, they set up cleaning stations where fish visit to have parasites, dead skin and mucus removed. In the aquarium, they may continue this instinctive behaviour, often approaching fish confidently and picking at leftover food and detritus. They are also excellent scavengers, helping to keep the tank tidy between maintenance sessions.
This species is reef-safe and generally peaceful, making it suitable for many community marine aquariums. With stable water conditions, appropriate hiding places and a varied diet, Lysmata amboinensis can live for several years and become a much-loved part of your reef display. As with all live marine livestock, we recommend acclimating carefully on arrival. We offer fast UK delivery and a live arrival guarantee for added peace of mind.

Lysmata amboinensis is native to the tropical Indo-Pacific, including reefs and lagoons where it lives among coral rubble, rocky crevices and sheltered reef structures. In nature, it often occupies cleaning stations, where fish gather to be serviced by the shrimp. This mutualistic relationship is one of the reasons the species is so fascinating in home aquariums.
The species is adapted to warm, stable marine environments with plenty of hiding spaces and moderate water movement. It is not a burrowing shrimp and does not require sand, but it does appreciate rockwork, overhangs and secure caves where it can retreat when moulting or resting. Because it is naturally social and active, it is best kept in a well-established aquarium with stable chemistry and low levels of aggression.
A mature marine aquarium of at least 100 litres is recommended for a single cleaner shrimp, though larger tanks are always better for long-term stability. A reef-style aquascape with live rock, caves and ledges will provide both shelter and grazing surfaces. Good filtration, regular water changes and stable salinity are essential, as shrimp are sensitive to sudden swings in water quality.
Keep temperature between 24 and 27°C, with pH held steady around 8.1 to 8.4. Specific gravity should remain in the typical reef range of 1.023 to 1.026. Avoid copper-based medications and be cautious with any treatments that are not explicitly safe for invertebrates. Shrimp also need stable iodine and mineral availability to support healthy moulting, so consistent maintenance is more important than heavy feeding.
Provide gentle to moderate flow and ensure there are no sharp intakes or uncovered pump areas where the shrimp could become trapped. A tight-fitting lid is not essential for this species, but a secure aquarium is always sensible in marine systems. When introducing new shrimp, drip acclimation is strongly recommended to reduce stress from changes in salinity and temperature.
Cleaner shrimp are generally hardy once settled, but they do best in established aquariums rather than brand-new marine setups. They may hide for a short period after moulting, which is normal. During this time, avoid disturbing them and ensure there are plenty of hiding places. Their antennae and delicate limbs can be damaged by rough handling, so always transfer them carefully.
Lysmata amboinensis is an omnivorous scavenger with a broad appetite. In the aquarium it will feed on leftover meaty foods, frozen marine preparations, pellet foods, and naturally occurring detritus. It may also pick at parasites or dead tissue on fish, although this should not be relied upon as a substitute for proper fish health management.
Offer a varied diet several times per week, including small portions of marine pellets, mysis shrimp, chopped krill, enriched brine shrimp and other quality frozen foods. Feed sparingly to avoid excess waste, as shrimp are opportunistic and will quickly find leftovers. In a well-stocked reef tank, they may also graze throughout the day on fine organic matter and uneaten food particles.
Because cleaner shrimp are active and social, they often learn to take food directly from feeding tongs or from the substrate. This makes target feeding easy and enjoyable to watch. Remove any uneaten food after a short period to maintain water quality, especially in smaller marine systems.
Cleaner shrimp are among the most peaceful marine invertebrates available and are usually compatible with a wide range of reef-safe fish. They do well with clownfish, gobies, blennies, wrasses, tangs, dwarf angelfish and many other non-aggressive species. They can also be kept with other peaceful invertebrates such as snails, hermit crabs and corals.
However, they should not be placed with predatory or highly aggressive fish that may view them as food. Large triggers, puffers, hawkfish, lionfish, moray eels and some large wrasses can pose a risk. Even fish that are generally reef-safe may occasionally nip at shrimp, particularly if the shrimp is small or newly introduced. Providing plenty of hiding places helps reduce stress and improves survival.
In groups, Lysmata amboinensis can be kept singly, in pairs or in small groups if the aquarium is large enough and well established. They are not usually territorial with their own kind, although they may compete for food if the tank is underfed. Their peaceful nature and useful scavenging habits make them a favourite for reef keepers of all experience levels.
