Sexy Shrimp Care Guide [2023]

If you’re looking to add some personality and color to your saltwater aquarium, consider adding sexy shrimp. These small, colorful shrimp are a popular choice among aquarium enthusiasts due to their interesting appearance and playful behavior. In this comprehensive guide, we’ll cover everything you need to know about sexy shrimp, including their origin, appearance, tank setup, water parameters, diet and feeding, behavior, breeding, and common health issues.

Origin of Sexy Shrimp

Sexy shrimp, also known as Thor amboinensis, are a species of shrimp native to the Indo-Pacific region. They are commonly found in shallow reef environments and can be found from the coast of East Africa to the west coast of Central America.

Appearance of Sexy Shrimp

Sexy shrimp are a small species of shrimp, typically growing to a maximum size of around 2.5 cm (1 inch) in length. They have a transparent body with distinctive bright red or orange bands on their legs and tail. The males are typically smaller than the females and have a more slender body shape.

Tank Setup for Sexy Shrimp

To provide a suitable environment for sexy shrimp, a well-established reef tank with plenty of live rock, corals, and other hiding places is recommended. A tank size of at least 10 gallons is necessary to accommodate a small group of sexy shrimp. They are not particularly active swimmers, so a tall tank with ample hiding places is preferable. A mature aquarium with stable water parameters is essential as sexy shrimp are sensitive to fluctuations in water chemistry.

Live rock provides a natural habitat for the shrimp to forage and hide in. The rocks can also serve as a biological filtration system for the tank. The addition of live sand will encourage the growth of beneficial bacteria, which will contribute to the health of the aquarium. Coral is another essential element for a sexy shrimp tank. Soft and LPS corals can provide a perfect place for the shrimp to hide while adding to the aesthetics of the tank.

It is essential to keep the water parameters stable and in line with the species’ requirements. Water temperature should be maintained between 75-80°F, with a pH range of 8.1-8.4 and specific gravity of 1.023-1.025. Proper lighting should also be provided, with low to moderate intensity light being ideal.

It is also recommended to provide a gentle water flow with the help of a wavemaker or powerhead. Sexy shrimp are not strong swimmers and require a constant flow of water to breathe properly. A protein skimmer can also be installed to remove organic waste from the water, but it should be carefully adjusted to avoid removing essential nutrients that the shrimp require. Regular water changes and maintenance of good water quality is vital for the health of the shrimp.

Diet and Feeding of Sexy Shrimp

Sexy shrimp are omnivores and will eat a variety of foods in the wild, including small invertebrates, algae, and detritus. In a home aquarium, they can be fed a varied diet that includes both meaty and plant-based foods. They can be fed small pieces of shrimp, fish, and other meaty foods, as well as flake or pellet foods, algae wafers, and vegetable matter.

It’s important to note that overfeeding can lead to poor water quality and can cause health problems for the shrimp, so it’s best to only provide as much food as they can consume in a few minutes. Additionally, it is recommended to feed them small amounts multiple times a day rather than one large feeding. This will help ensure that they receive a balanced and varied diet while also reducing the risk of overfeeding. Providing a calcium supplement is also recommended, as it will help the shrimp to form and maintain a healthy exoskeleton.

Behavior of Sexy Shrimp

When keeping sexy shrimp in a home aquarium, it is important to provide them with appropriate tank mates. They are generally peaceful and can be kept with other non-aggressive invertebrates such as snails, hermit crabs, and other small shrimp species. However, it is not recommended to keep them with larger, aggressive fish or crabs that may harm or eat them.

It is important to note that while sexy shrimp are generally peaceful, they can become territorial towards their own species if there is not enough space or hiding places in the tank. To prevent aggression, it is recommended to keep a maximum of one male per tank and maintain a ratio of two or three females for each male.

If kept in appropriate conditions, sexy shrimp can live for up to two years in a home aquarium. They are relatively easy to care for and are a popular addition to reef tanks due to their playful nature and striking appearance.

Breeding of Sexy Shrimp

Breeding sexy shrimp in captivity is a rewarding experience, but it requires specific conditions and patience. A well-established tank is necessary, with plenty of hiding places for the shrimp to lay their eggs. Once the shrimp have paired off, they will go through a courtship process before mating. During this process, the male will dance around the female and release pheromones to attract her. If successful, the female will lay her eggs on the underside of a hard surface.

It’s important to note that sexy shrimp larvae require a specific diet to survive. They need to be fed a diet of plankton, and the water flow in the tank must be adjusted to allow the larvae to feed. Additionally, the larvae require constant care, including frequent water changes and specialized feeding methods. It is recommended that only experienced hobbyists attempt to breed sexy shrimp in captivity.

Common Health Issues of Sexy Shrimp

Like all aquarium creatures, sexy shrimp can be susceptible to health issues such as infections, parasites, and stress. Maintaining good water quality and providing a balanced diet can help prevent these issues. In case of an infection, it’s important to quarantine the affected shrimp and treat with appropriate medications.

In addition to maintaining good water quality, it’s important to keep an eye out for any signs of health issues in sexy shrimp. Some common signs of health problems include discoloration, lethargy, loss of appetite, and abnormal behavior.

External parasites like copepods, nematodes, and flukes can infect sexy shrimp, as well as bacterial and fungal infections. If you suspect a health issue, it’s important to act quickly and quarantine the affected shrimp to prevent the spread of the disease.

To prevent stress in sexy shrimp, it’s important to provide them with adequate hiding places and space. Overcrowding can cause stress and lead to health problems, so it’s important to maintain appropriate stocking levels in the tank.

Regular water changes and maintaining stable water parameters can also help prevent stress and keep sexy shrimp healthy. Testing water parameters such as pH, ammonia, and nitrate levels can help ensure that the tank is a suitable environment for these sensitive creatures.


In conclusion, the sexy shrimp is a fascinating and delightful addition to any reef aquarium. These tiny shrimp are colorful, active, and playful, and they can form symbiotic relationships with anemones. To keep them healthy and thriving in a home aquarium, it’s important to provide a well-established tank with plenty of hiding places and a balanced diet. While breeding them in captivity can be challenging, it is possible with the right conditions. With proper care, sexy shrimp can live up to two years in a home aquarium and provide endless entertainment and beauty.
