Artbeschreibung
Geographical Origin and Habitat: Lysmata ternatensis is native to the warm tropical waters of the Western Indo-Pacific. Its geographical range extends from the Seychelles and East Africa to Indonesia, the Philippines, the Ryukyu Islands of Japan, and the Great Barrier Reef in Australia. It primarily inhabits shallow coral reefs, rocky crevices, and seagrass beds at depths of 2 to 20 meters, where it finds safety in sheltered microhabitats.
Taxonomy: Belonging to the family Lysmatidae, it is classified under the genus Lysmata, which includes well-known cleaner shrimps. It features long, white antennules used as tactile sensory organs and to advertise its presence to fish seeking cleaning services. The body is segmented and equipped with thin walking legs and small anterior chelae (claws) adapted for picking off parasites and dead tissue from client fish.
Social Behavior: This shrimp has a peaceful, somewhat cryptic behavior, with primarily crepuscular and nocturnal habits. It spends daylight hours hiding in rock crevices or under ledges, emerging when food is introduced or during the night. It is a social species that can be safely housed in small groups. It actively participates in removing external parasites from reef fish in the aquarium.
Coloration and Sexual Dimorphism: The coloration is characterized by red or orange longitudinal stripes running along the length of its semi-translucent body. The antennae and legs exhibit delicate reddish and whitish bands. There is no external visual sexual dimorphism, as mature individuals are simultaneous hermaphrodites, possessing both functional male and female reproductive organs.
Pflege, Zucht und Mitbewohner
Tank Setup: Requires an aquarium of at least 50 liters with plenty of live rock arranged to create crevices, small caves, and shaded areas where the shrimp can hide during the day. The tank should be well-established and stable. Water movement should be moderate to low in its preferred sheltering areas to prevent it from being swept away.
Diet and Feeding: It is an opportunistic omnivore and scavenger. In the aquarium, it feeds on organic debris, leftover fish food (pellets, flakes), and frozen foods like mysis, brine shrimp, and finely minced krill. It also performs cleaning duties, consuming ectoparasites from the skin, fins, and gills of cooperative fish that visit its cleaning station.
Water Quality: Maintain stable marine parameters: temperature 22-27 °C, pH 8.1-8.4, specific gravity 1.023-1.025, and KH 8-12. Adequate levels of calcium, magnesium, and iodine are essential for a successful molting process. This shrimp is highly sensitive to copper-based treatments, high nitrate levels, and sudden salinity changes.
Compatibility and Tankmates: It is 100% reef safe and will not harm corals, clams, or anemones. It coexists peacefully with most community fish and other peaceful invertebrates. Do not house it with large predatory fish (such as hawkfish, large wrasses, groupers, or puffers) that will readily prey upon and consume the shrimp, especially after molting.
Aquarium Breeding: Spawning occurs frequently in the aquarium, but rearing the larvae is extremely challenging. Since they are simultaneous hermaphrodites, any two mature individuals can mate. The fertilized eggs are carried under the abdomen as a green mass until hatching. The planktonic larvae are released at night and require specialized rearing systems.
Risks and Diseases: The primary health risk is molting failure, which can be fatal. Ensure adequate iodine levels are maintained to facilitate the shedding of the old exoskeleton. During and immediately after molting, the shrimp is soft and vulnerable, hiding in the rocks for a few days. Acclimate new specimens carefully using the drip method to avoid osmotic shock.

Wirbelloses Profil
- Diät
- Omnivore
- The Lysmata ternatensis is generally considered an opportunistic omnivore that will scavenge for leftover food, detritus, and small organisms. In the home aquarium, its diet should be supplemented with a variety of meaty foods such as frozen mysis shrimp, brine shrimp, and high-quality sinking pellets. Providing a varied diet ensures they receive the necessary nutrients for growth and molting. Feeding them targeted amounts helps prevent starvation while keeping the aquarium clean.
- Ökologische Rolle
- Cleaner
- In its natural habitat, the Lysmata ternatensis serves as a valuable cleaner and scavenger, helping to control detritus and organic waste. By consuming uneaten food and dead organic matter, it plays a critical role in nutrient recycling within the reef ecosystem. Some species within this group also engage in symbiotic relationships with other marine life, providing cleaning services in exchange for food. Their presence indicates a healthy and balanced marine environment.
- Erwachsenengröße
- 5.5 cm
- Sprungrisiko
- Yes
- While not notorious escape artists, the Lysmata ternatensis can be startled easily and may dart unpredictably when frightened. In open-top aquariums, this sudden burst of speed could potentially cause them to launch out of the water. It is advisable to use a tight-fitting lid or a mesh screen top to prevent any accidental escapes. Minimizing sudden movements or aggressive tank mates will also reduce the likelihood of jumping behavior.
- Stoßempfindlichkeit
- High
- The Lysmata ternatensis is quite sensitive to sudden changes in water parameters such as salinity, temperature, and pH. Rapid fluctuations can cause severe osmotic shock, leading to stress, failed molts, or immediate death. It is highly recommended to use a slow drip acclimation method over several hours when introducing them to a new aquarium. Consistent water quality and stability are paramount for their long-term survival and health.
- Kalzium und Mineralien
- Medium
- Proper calcium levels are essential for the Lysmata ternatensis to successfully build and maintain its exoskeleton. Along with calcium, trace elements like iodine and magnesium must be kept at optimal marine levels to facilitate the molting process. A lack of sufficient calcium can result in soft shells, deformities, and ultimately fatal molting complications. Regular water changes with high-quality salt mix usually provide adequate amounts of these crucial minerals.
- Häutung
- Regular
- Molting is a vulnerable time for the Lysmata ternatensis, during which it sheds its old exoskeleton to grow a new, larger one. Following a molt, the invertebrate will hide in the rockwork for a few days until its new shell hardens completely. During this period, they are highly susceptible to predation and physical damage from tank mates. It is best to leave the discarded exoskeleton in the tank, as they often consume it to reclaim valuable minerals.
- Reproduktion
- Oviparous
- Breeding the Lysmata ternatensis in a home aquarium can be challenging due to the complex larval stages and dietary needs of the offspring. These invertebrates often carry their eggs under their abdomen until they hatch into planktonic larvae. Raising the delicate larvae requires specialized rearing tanks and constant supplies of specific microscopic live foods. Although spontaneous spawning is common in well-fed adults, successful rearing to maturity is rarely achieved by casual aquarists.
- Kompatibilität & Tankkameraden
- Reef safe
- The Lysmata ternatensis is generally peaceful and can be safely housed with a wide variety of reef-safe fish and corals. Care should be taken to avoid keeping them with large, aggressive fish such as triggerfish, puffers, or large wrasses that might view them as a meal. They are usually tolerant of other peaceful invertebrates, though some territorial squabbles may occur with closely related species. Providing ample hiding spots among live rock will help them feel secure and reduce stress.
