Sexy Shrimp Care: Tank Setup, Diet, Tank Mates, Diseases & More

Ever since I started my journey with reef aquariums, I’ve been fascinated by the vibrant world of marine life, and the sexy shrimp quickly became one of my favorite inhabitants. These small, colorful crustaceans, known scientifically as Thor amboinensis, are perfect additions to nano and larger reef tanks alike. They’re known for their bold markings, unique movements, and compatibility with a variety of coral and tank mates, making them an exciting addition for aquarium hobbyists.

Sexy Shrimp require a tank size of at least 10 gallons, water temperature between 72-78°F, and a pH range of 8.1-8.4. They are scavengers and need a varied diet of high-quality pellets or flakes, as well as occasional live or frozen foods. They also require hiding places and a well-planted aquarium. Regular water changes and tank maintenance are important for their health.

When I first introduced sexy shrimp into my reef tank, I couldn’t help but be captivated by their quirky, intriguing behavior. Their alluring name comes from their peculiar and somewhat seductive dance, where they rhythmically move their abdomens in an undulating motion. But beyond their entertaining charms, these little shrimp play a crucial role in maintaining the overall health and cleanliness of the reef ecosystem.

To properly care for these amazing creatures, it’s essential to create a suitable and environmentally friendly home for them. Their ideal habitat should consist of plenty of hiding spots amongst the coral and rocks, as well as a stable temperature ranging from 72 to 78 degrees Fahrenheit. Make no mistake – investing time in setting up the right environment for your sexy shrimp will reward you with endless delightful and quirky moments, as it did to me.

Sexy Shrimp

Species Summary


The sexy shrimp, scientifically known as Thor amboinensis, are fascinating inhabitants of coral reefs, which I discovered on one of my diving trips. They are originally from the Indo-Pacific region.


In my experience caring for sexy shrimp, I’ve observed that they have a lifespan of approximately 2-3 years when kept in a well-maintained aquarium.


Sexy shrimp are strikingly beautiful creatures, with vibrant colors and transparent bodies. They have white spots along their carapace and abdomen, while their tail is adorned with an elegant fan-like structure. I often find myself captivated by them.


These small critters typically reach lengths of about 1.5 to 2 cm, making them perfect for nano reef tanks or smaller aquariums.

Growth Rate

From my observations, the growth rate of sexy shrimp is relatively slow. They tend to reach their full size within a year.

Behavior & Temperament

One thing I truly appreciate is how peaceful and reef-safe these little creatures are. They’re known for their unique, rhythmic dance-like movements, which is where their name originates. Sexy shrimp are social and tend to form small groups.

Male vs Female

It can be challenging to differentiate between male and female sexy shrimp. Males are slightly smaller and less vibrant in color than the females, but without close examination, it’s difficult to tell them apart.

Tank Setup

Tank Size

When I first started caring for sexy shrimp, I learned the importance of choosing the right tank size. A minimum of 5 gallons is recommended for a small group of these shrimp. This provides them with enough space to roam around and establish their territory.


These shrimp require moderate lighting, which helps promote algae growth – an essential food source for them. I found that using LED aquarium lights with a timer works best for maintaining consistent lighting conditions.

Filtration & Aeration

Filtration and aeration are crucial in maintaining water quality. A quality sponge filter connected to an air pump works wonders for these small tanks, as it gently filters the water without creating strong currents that could stress the shrimp.


Sexy shrimp are tropical creatures, so maintaining a stable temperature between 72°F and 78°F is essential. I use a small, adjustable heater to ensure my tank stays within this range.


In my experience, a thin layer of sand substrate has been the most suitable choice for sexy shrimp. It allows them to burrow and scavenge for food while also being easy to clean.


I like to include various hiding spots for my sexy shrimp by using items like small rocks, shells, and terracotta pots. This mimics their natural environment, reduces stress, and keeps them more active.


Adding live plants to your tank not only provides cover for your shrimp but also aids in maintaining water quality. Some of my favorite plants to include are java moss, Anubias, and various ferns.

Remember to consider these factors when setting up a tank for your sexy shrimp. With the right environment, you’ll be able to enjoy these fascinating creatures for years to come.

Water Quality

Water Temperature

Ideal temperature range: 72-78°F (22-26°C)

I remember when setting up my sexy shrimp tank, I carefully monitored the water temperature. It’s crucial to keep it stable within the ideal range, as even slight fluctuations can stress the shrimp and reduce their vibrant colors.

Water pH

Optimal pH level: 8.1-8.4

Another aspect I pay close attention to is the water pH. Sexy shrimp thrive in alkaline water, and maintaining a slightly higher pH is important for their overall health and well-being.

Water Hardness

Recommended dKH: 8-12

Recommended Mg levels: 1250-1350 ppm

When it comes to water hardness, both carbonate hardness (dKH) and magnesium (Mg) levels play a key role. I found it helpful to test these parameters regularly and adjust them accordingly to maintain a stable environment.

Water Changes

  • Routine water changes: 10-20% every two weeks
  • Consistent schedule: Avoid large water changes and try not to skip or delay scheduled maintenance

I learned that regular, small water changes are essential for maintaining a healthy habitat for my sexy shrimp. Sticking to a consistent schedule not only ensures optimal water quality but also prevents sudden fluctuations in water conditions that could stress the shrimp.

Tank Maintenance

When I first started keeping sexy shrimp, I quickly realized that maintaining the tank is essential for their health and happiness. Let me share my insights with you on how to achieve this.

First of all, regular water changes are crucial. I usually do a 20% water change every 2 weeks. This helps to keep the water pristine and ensures a stable environment for the shrimp.

In addition, it’s essential to monitor water parameters like ammonia, nitrite, nitrate, pH, and salinity. I use a simple test kit to check these values weekly. This allows me to make adjustments to the water chemistry as needed.

Another important aspect of tank maintenance is cleaning the tank itself. I make sure to remove any algae buildup on the glass walls and equipment with an algae scraper or magnetic cleaner.

Don’t forget filtration. I have found that using a sponge filter works great for sexy shrimp tanks. It is efficient and doesn’t produce strong currents that could bother the shrimp. Clean the sponge filter once a month.

Lastly, don’t overlook substrate and decorations. I use a mix of sand and crushed coral for my sexy shrimp tank. Occasionally, I gently siphon the substrate to remove any accumulated debris. Also, clean the decorations during water changes to prevent algae buildup.

By following these steps, I have been able to maintain a healthy and visually appealing tank for my sexy shrimp to thrive in. Stick to these guidelines, and you’ll enjoy watching your little invertebrate friends flourish!

Tank Mates

Compatible Fish Species

As an aquarist, I’ve found that sexy shrimps can coexist harmoniously with various reef-dwelling fish. Some good tank mates include:

  • Clownfish: They are peaceful and won’t bother your sexy shrimps.
  • Firefish: Their timid nature makes them ideal companions.
  • Gobies: They are generally small and won’t pose a threat.

Remember, it’s essential to add fish slowly, observing their interactions to ensure a peaceful tank community.

Incompatible Fish Species

Unfortunately, not all species make good tank mates. From my experience, the following fish should be avoided because they may harm or consume your sexy shrimps:

LionfishPredatory and will eat shrimp
AngelfishMay nip at or eat the shrimp
Large WrassesAggressive and can attack shrimp

It’s critical to research specific species of fish you wish to house with your sexy shrimps to ensure the compatibility of tank mates.

What To Feed

In my experience, sexy shrimp thrive on a diverse diet consisting of both meaty and plant-based foods. Some favorites include:

  • Frozen foods: mysis shrimp, brine shrimp, and plankton
  • Dry foods: high-quality pellet or flake foods
  • Vegetation: finely chopped spinach or seaweed


Feeding these curious little creatures should be done 2-3 times a day. I’ve found that a consistent feeding schedule helps keep them active and healthy.


Here are some tips to ensure a successful feeding experience for your sexy shrimp:

  1. Quantity: Feed them small amounts at each feeding; overfeeding can lead to poor water quality.
  2. Variety: Rotate between different food types to provide a well-rounded diet and prevent boredom.
  3. Observe: Lastly, always monitor their eating habits and adjust the diet as necessary.

One day, I noticed one of my sexy shrimp had a habit of stealing food from his tankmates. I had to get creative in finding ways to ensure everyone got their fair share of food. Be prepared for such unexpected behaviors and adapt as needed!

Common Diseases


In my experience caring for sexy shrimp, I’ve encountered a few common diseases that can affect these fascinating creatures. One such ailment is bacterial infection, which can manifest as shell rot or necrosis. Another frequent issue is the presence of parasites, such as gill or external parasites.


A bacterial infection typically presents with a visible deterioration of the shrimp’s exoskeleton. For instance, I once noticed discoloration and pitting on the shell of one of my sexy shrimp. Parasites, on the other hand, may cause erratic swimming or lethargy in the affected shrimp.


When I dealt with bacterial infection in my sexy shrimp tank, my go-to treatment included:

  • Administering a broad-spectrum antibiotic, such as Erythromycin
  • Isolating the affected shrimp for targeted treatment

For parasites, effective treatments I’ve used are:

  • Praziquantel for gill or internal parasites
  • Formalin to eliminate external parasites


To minimize the risk of disease in my sexy shrimp tank, I’ve employed several preventive measures, such as:

  • Maintaining optimal water quality through regular water changes
  • Avoiding overfeeding or underfeeding the shrimp
  • Quarantining new additions to the tank before introducing them to the main setup

By following these guidelines, I’ve managed to maintain a healthy and thriving environment for my sexy shrimp, and I hope you find them helpful too.

Signs of a Healthy Sexy Shrimp

A healthy Sexy Shrimp is a sight to behold in any aquarium. I remember the first time I saw one, and I couldn’t take my eyes off its vibrant colors and energetic movements.

One key sign of a healthy Sexy Shrimp is its bold and lively colors. These beauties sport red and white bands on their legs and have a vibrant, translucent body.

Another aspect to look for is their active behavior. They should be:

  • Constantly moving around the tank
  • Grazing on algae and other particles
  • Engaging in their unique ‘dancing’ movements

Sexy Shrimp are also known to display clean, well-maintained exoskeletons. This is important, as it shows they’re properly molting and growing as they should be.

A healthy appetite is crucial in any marine creature. As for the Sexy Shrimp, they should be:

  • Feeding on a variety of diets, such as baby brine shrimp or pellet food
  • Eagerness to eat when food is introduced to the tank

Lastly, always pay attention to their social behavior. Even though I’ve seen occasional scuffles between individuals, generally, they should coexist peacefully with other tank mates.

In summary, to ensure a healthy Sexy Shrimp in your aquarium, watch out for their vibrant colors, active behavior, clean exoskeletons, good appetite, and social interactions. I can assure you, with proper care, these charming creatures will liven up any aquatic environment.

Signs Your Sexy Shrimp is Sick

I once had a sexy shrimp that didn’t seem quite right. It showed some unusual behavior, which got me concerned. Here are some key signs that your sexy shrimp may be sick.

  1. Lethargy: If your shrimp is less active than usual, this could signal illness.
  2. Loss of appetite: A healthy shrimp should have a good appetite. If it stops eating or eats less, it might be sick.
  3. Rapid breathing: Notice your shrimp breathing faster than usual? This could indicate stress or illness.
  4. Discoloration: Keep an eye out for unusual changes in color, such as dullness or spots.
  5. Abnormal behavior: If your shrimp is swimming strangely, hiding more than usual, or acting differently, it might be a red flag.

It’s essential to monitor your sexy shrimp’s health and address any issues promptly. If you suspect your shrimp is sick, consult a knowledgeable aquarist or aquatic veterinarian for guidance. Caring for a sexy shrimp can be very rewarding, and catching potential problems early is crucial for its wellbeing.


Breeding Setup

When I first started breeding sexy shrimps, I set up a separate tank specifically for the process. It’s important to maintain stable water parameters, so make sure to choose a tank of around 5-10 gallons with proper filtration and heating systems in place.

How To Breed

To encourage my sexy shrimps to breed, I gradually raised the water temperature to 80-82°F (27-28°C) and provided them with plenty of hiding spots. These can include:

  • Live rock
  • Coral
  • PVC pipes

Keep an eye out for the female carrying eggs under her abdomen. When you spot this, try to gently move her into the breeding setup. I usually did this with a turkey baster to minimize stress.


Once the female releases larvae, providing them with a suitable diet is crucial. My go-to food choices for the larvae were:

  • Baby brine shrimp
  • Copepods
  • Plankton

I maintained a regular feeding schedule—twice daily—and observed them closely. It’s important to keep the water clean, so I conducted a partial water change every few days.

Seeing the larvae metamorphose into tiny shrimps was truly rewarding! Just remember to be patient and attentive throughout the process. Good luck!
