These little critters, also known as roly-polies, pillbugs, or woodlice, are becoming increasingly popular in the pet-keeping world. Not only are they fascinating to watch, but they also play a vital role in bioactive terrariums and can be surprisingly rewarding pets. This guide will cover everything you need to know about keeping isopods as pets, from understanding their basic needs to setting up their habitat and ensuring they thrive. So, let’s dive in and explore the wonderful world of isopod keeping!
What are Isopods?
Isopods, those tiny crustaceans we often find under rocks and logs, are much more than just garden inhabitants. These little guys belong to the suborder Oniscidea within the order Isopoda. Unlike insects, isopods are actually more closely related to shrimp and crabs! They are characterized by their segmented bodies, seven pairs of legs, and the ability to roll into a ball when threatened – a behavior that has earned some species the nickname "roly-poly." Understanding the biology and behavior of isopods is crucial for providing them with the right environment and care in captivity.
Isopods are detritivores, meaning they primarily feed on decaying organic matter. This makes them excellent cleanup crew members in terrariums, where they help break down waste and prevent mold growth. In the wild, isopods play a vital role in nutrient cycling, contributing to the health of ecosystems by decomposing leaf litter and other organic debris. Their diet consists mainly of decaying leaves, wood, fungi, and even animal waste. This diverse diet ensures that they get all the necessary nutrients to thrive. When keeping isopods as pets, it’s important to mimic their natural diet by providing them with a variety of organic materials. This not only keeps them healthy but also encourages their natural scavenging behavior, making them more interesting to observe.
There are thousands of isopod species found all over the world, each with unique characteristics and adaptations. From the common Pillbug to the vibrant Cuban Isopod, the diversity within this group is astounding. Some species prefer moist environments, while others are more tolerant of drier conditions. Some are tiny, measuring only a few millimeters in length, while others can grow to be several centimeters long. This variety means that there’s an isopod species out there for just about every pet keeper. Whether you’re looking for a colorful display animal or a hardworking cleanup crew for your terrarium, understanding the different types of isopods and their specific needs is the first step in successful isopod keeping.
Why Keep Isopods as Pets?
Keeping isopods as pets comes with a plethora of benefits that make them an appealing choice for both novice and experienced pet enthusiasts. Firstly, they are incredibly low maintenance. Unlike many other pets, isopods don't require daily attention or extensive care routines.

Setting Up Your Isopod Habitat
Creating the perfect habitat for your isopods is essential for their health and well-being. A well-designed enclosure will mimic their natural environment and provide them with everything they need to thrive. Firstly, you’ll need a suitable container. A plastic tub, glass terrarium, or even a repurposed storage container can work well, as long as it has a secure lid to prevent escapes and maintain humidity. The size of the container will depend on the number of isopods you plan to keep. A good rule of thumb is to provide at least one gallon of space for every 50 isopods.
Next, you'll need to create a proper substrate. The substrate is the foundation of your isopod habitat and provides them with food, shelter, and a place to burrow. A mixture of organic materials such as coco coir, peat moss, leaf litter, and decaying wood works well. This combination provides a variety of textures and nutrients that isopods need to thrive. Add a layer of sphagnum moss on top of the substrate to help retain moisture. It’s crucial to ensure that the substrate is deep enough for the isopods to burrow and explore, ideally at least a few inches deep. Avoid using soil that contains pesticides or fertilizers, as these can be harmful to your isopods.
Maintaining the right humidity level is crucial for isopod health. Isopods require a moist environment to breathe and prevent desiccation. You can maintain humidity by misting the enclosure with water regularly. The frequency of misting will depend on the type of isopod you are keeping and the ambient humidity in your home. Generally, you want to keep the substrate moist but not waterlogged. A good way to check the humidity is to monitor the condensation on the sides of the enclosure. If there is excessive condensation, you may need to reduce the amount of misting. Providing a humidity gradient within the enclosure is also beneficial, allowing the isopods to choose the moisture level they prefer. This can be achieved by misting one side of the enclosure more heavily than the other. In addition to substrate and humidity, provide plenty of hiding spots. Pieces of bark, rocks, and leaf litter offer shelter and security, reducing stress and promoting natural behaviors. These elements also add visual interest to the enclosure, making it more aesthetically pleasing. With the right setup, your isopod habitat will not only be functional but also a beautiful miniature ecosystem.
Feeding Your Isopods
Providing your isopods with a balanced and nutritious diet is essential for their health and longevity. Isopods are detritivores, which means they primarily feed on decaying organic matter. Mimicking their natural diet in captivity is key to keeping them happy and thriving. A varied diet that includes a mix of plant-based and protein-based foods will ensure they get all the nutrients they need. Decaying leaves are a staple food for isopods. Oak, maple, and beech leaves are all excellent choices. Collect the leaves from pesticide-free areas and allow them to dry before adding them to the enclosure. You can also supplement their diet with other plant materials such as vegetable scraps, fruit peels, and dried flowers. Be sure to remove any uneaten food regularly to prevent mold growth.
Protein is also an important part of an isopod's diet, especially for breeding females. You can provide protein by offering them small amounts of fish flakes, dried shrimp, or even crushed mealworms. These protein sources should be offered sparingly, as too much protein can lead to health problems. A good rule of thumb is to provide protein once or twice a week. Calcium is another essential nutrient for isopods, as it is needed for shell development and overall health. You can provide calcium by adding crushed eggshells, cuttlebone, or calcium carbonate powder to the enclosure. These calcium sources will also help buffer the pH of the substrate, creating a more stable environment.
Water is also vital for isopods, and they obtain it primarily through the moisture in their environment. Regularly misting the enclosure will provide them with the water they need. You can also provide a shallow dish of water with pebbles or cotton balls to prevent them from drowning. Always use dechlorinated water, as chlorine can be harmful to isopods. Monitoring your isopods' feeding habits will help you determine if they are getting enough food. If you notice that they are actively scavenging and consuming the food you provide, it's a good sign that they are healthy and well-fed. If you see a lot of uneaten food, you may need to reduce the amount you are offering. With a little experimentation, you'll find the right balance to keep your isopods happy and thriving. A well-fed isopod colony is a healthy and active colony.

Troubleshooting Common Issues
Even with the best care, you might encounter some common issues when keeping isopods as pets. Being able to identify and address these problems quickly will help ensure the health and well-being of your colony. One of the most common problems is mold growth in the enclosure. Mold can thrive in the moist environment that isopods require, but excessive mold can be harmful to them. To prevent mold growth, ensure good ventilation by adding air holes to the enclosure or using a mesh lid. Regularly remove any uneaten food and decaying organic matter, as these can contribute to mold growth. If you do find mold, you can carefully remove it with a spoon or replace the affected substrate.
Another potential issue is a lack of breeding. If your isopods are not reproducing, it could be due to several factors. Ensure that the temperature and humidity are within the optimal range for your species. Insufficient food or protein can also hinder breeding. Try supplementing their diet with more protein-rich foods like fish flakes or dried shrimp. Additionally, overcrowding can stress the isopods and inhibit breeding. If your colony is too large for its enclosure, consider dividing it into multiple containers. Infestations of mites or other pests can also affect isopod health and breeding. Regularly inspect your isopods for any signs of pests, such as small, crawling insects or unusual behavior. If you find pests, you can try introducing predatory mites or using a mild insecticide specifically designed for use with invertebrates. Always follow the instructions carefully and avoid using harsh chemicals that could harm your isopods.
Desiccation is another common problem, especially in drier climates. Isopods require a moist environment to breathe and prevent dehydration. If your isopods are lethargic or appear shriveled, they may be suffering from desiccation. Increase the humidity in the enclosure by misting it more frequently. You can also add a layer of sphagnum moss to help retain moisture. Providing a water source, such as a shallow dish with cotton balls, will also allow the isopods to rehydrate. By addressing these common issues promptly and providing your isopods with the right care, you can ensure a healthy and thriving colony. Regular observation and attention to their needs will help you catch problems early and keep your isopods happy.
