About This Species
Basic Description
The Skunk Cleaner Shrimp is a popular and beneficial crustacean for saltwater aquariums, known for its active cleaning behavior and peaceful nature. This shrimp plays a valuable role by forming a symbiotic relationship with fish, gently removing parasites and dead tissue from their bodies. Its care level is considered straightforward, making it an excellent choice for those new to the marine hobby. It is a carnivore that readily accepts a variety of prepared foods, including frozen items, pellets, and flakes, and will also help with tank cleanup by consuming leftover food and detritus.These shrimps are moderately active and typically occupy the middle and bottom regions of the aquarium, often setting up a "cleaning station" on prominent rockwork. While generally peaceful and suitable for community tanks, they are best kept with non-aggressive fish that will not view them as a meal. They can be kept singly but are often seen in pairs or small groups. A notable characteristic is their tendency to explore, so a securely covered aquarium is essential to prevent them from climbing out. With their engaging behavior and useful function, they are a fascinating addition to any marine setup.
Detailed Description
A valuable inhabitant of Indo-Pacific coral reefs, the Skunk Cleaner Shrimp has translated its natural ecological role into a prized function within the marine aquarium. In the wild, it establishes "cleaning stations," often on coral heads or ledges, where fish of all sizes queue up to have ectoparasites and necrotic tissue meticulously removed. Replicating this environment is key to its well-being in captivity. An established aquarium with ample live rock provides crucial hiding places, especially during the vulnerable molting period, and allows the shrimp to establish its territory. It thrives in standard reef conditions, requiring stable, warm tropical water temperatures, moderate water flow to simulate its natural habitat, and consistent marine salinity and pH levels.Although it gains some nutrition from its cleaning duties, this must be supplemented with a regular, direct diet. As a carnivore, it requires daily offerings of meaty foods. A varied diet of high-quality frozen foods, sinking pellets, and flakes ensures its nutritional needs are met and supports its long-term health and vitality. Its scavenging nature also contributes to the tank's cleanliness as it consumes detritus and uneaten food.Socially, these shrimp are peaceful and can be kept individually or in pairs. A pair will often bond and work together, providing a fascinating behavioral display. Its small adult size and peaceful disposition make it compatible with a wide range of reef inhabitants, though caution should be exercised with large, predatory fish. As with all crustaceans, it will periodically molt its exoskeleton to grow. During this time, it may retreat for a few days until its new shell hardens. Due to a low metabolic rate, it contributes minimally to the aquarium's bioload but still requires pristine water conditions to flourish over its multi-year lifespan.
Scientific Description
Lysmata amboinensis is a decapod crustacean belonging to the family Lysmatidae, a group well-regarded for its numerous symbiotic cleaner species. Its morphology includes a laterally compressed body, an adaptation that facilitates movement and shelter within the complex structures of coral reef environments. Native to the vast Indo-Pacific region, this species plays a significant ecological role as a facultative cleaner. It engages in mutualistic symbiosis with a wide array of client fish, establishing cleaning stations where it removes and consumes ectoparasites, algae, and damaged tissue. This interaction is critical for maintaining the health and reducing the parasite load of local fish populations, thereby contributing to the overall stability of the reef ecosystem. Its widespread distribution and stable population have resulted in a classification of Least Concern on the IUCN Red List.Physiologically, L. amboinensis is adapted to the stable parameters of a tropical marine environment. It exhibits a low metabolic rate and corresponding low oxygen consumption, which is characteristic of an animal that is often stationary while waiting for client fish. This low metabolism results in minimal waste production, giving it a low bioload factor in closed aquatic systems. Like other marine invertebrates, it requires water with a standard concentration of total dissolved solids typical of seawater. The species exhibits protandric simultaneous hermaphroditism; individuals typically mature first as males before developing female reproductive capabilities, allowing any two individuals to potentially form a breeding pair. This reproductive strategy enhances its chances of successful propagation throughout its habitat.
Breeding Description
The captive breeding of the Skunk Cleaner Shrimp is a complex and challenging endeavor, primarily recommended for experienced and dedicated hobbyists. The difficulty does not lie in getting the shrimp to spawn, but rather in successfully raising the delicate larvae to the juvenile stage. For pairing, this species offers a unique advantage. They are protandric simultaneous hermaphrodites, meaning they begin life as males and later gain the ability to function as females as well. Consequently, any two individuals can form a pair, eliminating the need for sex identification. Once a pair is established in a healthy, stable environment, they will likely begin to reproduce without special intervention. One shrimp will carry a clutch of greenish eggs under its abdomen, attached to its pleopods (swimmerets). Over a few weeks, these eggs will develop and eventually hatch, typically after dark.The primary challenge begins when the eggs hatch, releasing a large number of tiny, planktonic larvae into the water column. These larvae must be collected and moved to a specialized larval-rearing tank, such as a Kreisel or similar circular aquarium, which is designed to keep them suspended with gentle water flow. The larvae are extremely sensitive and have a prolonged pelagic stage, undergoing multiple molts before metamorphosing into post-larval shrimp. During this extended period, they require a consistent supply of appropriately sized live foods. The initial diet must consist of microscopic foods like phytoplankton and rotifers. As the larvae grow, their diet can be gradually shifted to slightly larger foods like newly hatched Artemia nauplii. Maintaining immaculate water quality and providing the correct feeding regimen throughout the entire larval development is paramount and is where most breeding attempts fail. Success is marked by the larvae finally settling out of the water column as miniature versions of the adults.
