In this guide, I’ll share with you everything I’ve learned about keeping fairy shrimp in an aquarium, from the ideal tank setup to their diet and care. I’ll also delve into the various species of fairy shrimp, each with its unique characteristics and needs. By the end, you’ll have all the information you need to start your own fairy shrimp journey!
Fairy Shrimp’s Natural Habitat
Understanding the natural habitat of fairy shrimp is crucial if you’re planning to keep them in your aquarium. Their unique lifestyle and environmental needs set them apart from many other aquatic creatures you might be familiar with.
Fairy shrimp are inhabitants of temporary, often isolated bodies of freshwater such as vernal pools, dry lake beds, and even small puddles of muddy rainwater. These are areas that fill with water during rainy seasons but can completely dry out at other times. As such, fairy shrimp have evolved to have very short life cycles, usually a few weeks to a few months, allowing them to hatch, mature, breed, and lay eggs within the temporary existence of these water bodies.
The water in these habitats is typically still or has very little movement, which is why fairy shrimp can thrive without a water filter or flow in the aquarium. They also prefer well-lit environments, as many keepers have observed that fairy shrimp display brighter coloration when kept under direct light.
The conditions of the water in their natural habitats can vary greatly depending on the species and the specific location. Some fairy shrimp can tolerate different levels of salinity, while others require very specific conditions. Therefore, knowing the specific needs of the species you wish to keep is of utmost importance.
Temperature is another key factor in the life cycle of fairy shrimp. Different species of fairy shrimp thrive in different temperature ranges. For example, some species such as the Giant Fairy Shrimp prefer cooler temperatures, optimally between 45-60F for hatching. Others, like the Redtail Fairy Shrimp and Thai Fairy Shrimp, can survive in a wider range of temperatures, from 50-100F and 50-65F respectively.
These little creatures are truly a testament to the resilience and adaptability of life. By replicating their natural habitat as closely as possible in our aquariums, we can provide them with a comfortable environment in which they can thrive.
Choosing the Right Aquarium for Your Fairy Shrimp
Choosing the right aquarium for your fairy shrimp is a critical step in setting up a suitable environment for these unique creatures. Fairy shrimp are quite different from the typical fish or aquatic pets we commonly keep in aquariums, and as such, their needs are distinct.
Tank Size
One of the primary things to consider when choosing a fairy shrimp aquarium is the size. Fairy shrimp can be kept in relatively small containers, such as nano or pico tanks, or even in large bowls. The size of the container you choose will largely depend on the number of shrimp you plan to keep and the specific species, as some fairy shrimp grow larger than others.
No Filter Required!
Remember, fairy shrimp are adapted to live in standing water environments. That means that unlike many aquarium inhabitants, they do not require a water filter or a pump that creates a current in the water. In fact, strong filters can actually harm your fairy shrimp, especially the babies, by sucking them in. If you do choose to use a filter, make sure it’s a gentle one and consider covering it with a sponge to prevent any accidents.
Substrate
The substrate and decorations in the aquarium are largely a matter of personal preference. Some keepers prefer to keep the bottom of the tank bare, while others add a layer of sand or small pebbles. It’s also possible to include live plants or other decorations, but these are not necessary for the shrimp’s survival. If you choose to include plants, consider species that can thrive in still water and do not require a rich substrate or fertilization, as these could negatively impact the water quality for your shrimp.
Water
Water quality is another important factor to consider. Fairy shrimp generally do best in distilled or spring water. Tap water can contain chlorine and other chemicals that are harmful to fairy shrimp, so it’s best avoided unless you have a way to treat it with a dechlorinator
or use RO water and a buffer.
Regularly topping off the water to replace evaporation will help maintain a consistent water level.
Lighting
Lighting is also worth considering. As mentioned before, fairy shrimp are known to exhibit brighter coloration under direct light. Therefore, placing your aquarium in a well-lit area or providing artificial light can enhance the beauty of your shrimp.
Keep in mind that fairy shrimp are not great swimmers and can’t jump out of the water like some fish species, so a lid isn’t strictly necessary unless you have other pets or small children who might disturb the aquarium.
Feeding and Maintaining Your Fairy Shrimp
Caring for fairy shrimp involves providing them with the right nutrition and maintaining their habitat in a way that promotes their health and well-being.
Yeast Soup
Feeding fairy shrimp is an interesting task, as their diet is quite different from most aquarium pets. In the wild, fairy shrimps are filter feeders, straining tiny particles like bacteria, algae, and spores out of the water. In captivity, you can feed them a homemade mixture, often referred to as “yeast soup.” This soup is a mixture of one packet of dried yeast (baker’s or brewer’s), one teaspoon of sugar, and a big pinch of crushed fish food flakes dissolved in 1/3 cup of hot spring water. Mix it well and let it sit for an hour before feeding.
Once your yeast soup is ready, you can store it in the refrigerator or another cool place. To feed your shrimp, stir or shake the mixture thoroughly as it settles out quickly. Use an eyedropper or pipette to drip a few drops of the soup into the water.
The right amount of food will make the water slightly hazy but still see-through. If it becomes cloudy, it means you’ve overfed your shrimp. Overfeeding can lead to poor water quality and health problems for your shrimp, so if you notice the water becoming cloudy, stop feeding for a day or two until it clears up.
Feeding Your Fairy Shrimp Rice Bran
While the yeast soup mixture is a commonly used food source for fairy shrimp, some aquarists have found success with other food sources such as rice bran. Rice bran is the nutrient-rich outer layer of rice and is often used as a food supplement in aquaculture due to its high protein content and availability.
To use rice bran as food for your fairy shrimp, simply take a small amount and dissolve it in some water. The aim is to create a cloudy solution, much like when preparing the yeast soup. Once prepared, you can use an eyedropper or pipette to drip the rice bran solution into your fairy shrimp tank.
Feeding Your Fairy Shrimp Spirulina and Chlorella Algae
In addition to yeast soup and rice bran, fairy shrimp can also benefit from a diet that includes algae like spirulina and chlorella. These types of algae are rich in essential nutrients and can help support the health and growth of your fairy shrimp.
Spirulina and chlorella are both types of microalgae that are commonly used in the aquaculture industry due to their high protein content and nutritional profile. They’re also easy to use as food for fairy shrimp.
To feed your fairy shrimp spirulina or chlorella, you can purchase the algae in powdered form. Just like with rice bran, you’ll want to create a cloudy solution by mixing a small amount of the algae powder with some water. Once your solution is ready, you can add it to your tank using an eyedropper or pipette.
Just as with any other food source, it’s important to monitor the clarity of your tank’s water when feeding your fairy shrimp algae. If the water becomes too cloudy, it’s a sign that you’re overfeeding and you should reduce the amount of food you’re adding to the tank until the water clears up.
Do not Overfeed!
As with any food source, it’s essential to avoid overfeeding your fairy shrimp. Overfeeding can lead to poor water quality and potentially harm your shrimp. The water should be slightly hazy, but not overly cloudy. If the water becomes too cloudy, it’s a sign you should reduce feeding for a day or two until the water clears up.
Maintaining the water quality is another crucial aspect of fairy shrimp care. As mentioned before, use distilled or spring water for your shrimp and avoid tap water unless it’s been treated to remove harmful chemicals. Fairy shrimp don’t require filtration, but you will need to top off the water regularly to compensate for evaporation. Avoid drastic changes in water level, temperature, or quality, as these can stress your shrimp and potentially harm them.
Short Life
Another key part of maintenance is monitoring your shrimp’s health. Keep an eye out for any changes in their behavior or appearance, as these could indicate a problem. Remember, fairy shrimp have relatively short lifespans, so it’s normal for them to die off after a few weeks to a few months. However, sudden mass deaths could signal a problem with the water quality or other conditions in the tank.
Reproduction
Fairy shrimp reproduce by laying eggs, which can survive dry periods and hatch when conditions are right. If you notice tiny eggs in your aquarium, it’s a good sign that your shrimp are happy and healthy. You can choose to harvest these eggs to start a new generation of shrimp, or leave them be to hatch in their own time.

My Personal Experience with Fairy Shrimp
Having fairy shrimp as pets has been a truly rewarding and fascinating experience for me. When I first decided to get them, I was attracted by their unique life cycle and behavior. They provided something different from the typical fish or aquatic pets, and I was excited to embark on this new journey.
I started with Thai fairy shrimp. Unfortunately, my initial experience was challenging – the hatch rate was quite low, and the longest lifespan I observed was just 3 1/2 weeks. However, this didn’t discourage me. Instead, it motivated me to learn more and adjust my approach. I came to understand that the shrimp’s short lifespan was part of their natural cycle and not necessarily a sign of poor care. And while the low hatch rate was initially disappointing, it made the hatching of each shrimp feel all the more special.
After the Thai fairy shrimp, I decided to try raising Redtail fairy shrimp. I was attracted to their vibrant coloration and the contrast they would provide in the aquarium. The experience with the Redtails was yet another learning curve, and I found myself continually adjusting and improving my care methods.
What I’ve come to appreciate most about keeping fairy shrimp is the window they provide into a unique form of life. Watching them swim in their slow, graceful manner, seeing them filter-feed, and observing the hatching of the eggs has been nothing short of captivating. Despite their short lifespan, they’ve made a lasting impression on me.
My experience with fairy shrimp has taught me a lot, not just about these creatures themselves, but also about patience, observation, and the cycle of life. I’m looking forward to continuing my fairy shrimp journey and would encourage anyone interested in unique aquatic life to consider adding them to their home.
Happy Fairy Shrimp Keeping!
