Looks how to spot one
Exoskeleton
A chunky, rounded body with a hard, segmented exoskeleton. The back is marked with bold black and white stripes that vary between individuals. Like all true pill bugs, it can roll into a tight, armoured ball when disturbed.14
Personality what they are like
Zebra isopods are docile, slow-moving and easy to handle. They are active explorers, especially in the evening, and become more visible as the colony grows. They do not bite or sting and are safe for children to observe.21
Daily activity how busy a day looks
Low. They are content in a well-set-up terrarium with deep substrate, leaf litter and hiding spots. They are most active during dusk and night.24
Grooming and care the hands-on bits
Minimal. Provide a moisture gradient with one damp area and the rest drier. Good ventilation is essential. Remove uneaten fresh food after a day or two to prevent mould. Cuttlebone or crushed eggshell should always be available for calcium.26
Home where they are happiest
A terrarium of at least 5 gallons (18-20 litres) for a colony. Use a deep substrate of organic topsoil, flake soil and white-rotted hardwood, topped with leaf litter and cork bark hides. Keep at room temperature (18-25 °C) with moderate humidity and good airflow. They prefer a drier Mediterranean setup rather than a damp, still environment.276
Food basics what goes in the bowl
Detritivore. The main diet is decaying hardwood leaves and rotting wood, which should always be available. Supplement occasionally with vegetables, fruit and a little protein such as fish flake or dried shrimp. Calcium must be provided for healthy moulting.126
Company who they like around
Gregarious. They should be kept in groups of at least 10-20 to thrive. They are not aggressive and can be housed with other peaceful invertebrates. They are harmless to humans and pets.21
The story where it all began
The zebra isopod was first described scientifically in 1816 from specimens collected in southern France. Its bold black and white stripes made it stand out to early isopod enthusiasts, and it quickly became a staple in the hobby. Selective breeding has produced several colour morphs, including yellow, spotted and high-white varieties. Today it is one of the most popular isopods for display terrariums and bioactive vivariums.126
Recognised by the official bits
Popularity Very high among isopod hobbyists; one of the most commonly kept species.12

Owner questions the things everyone asks
How often should I feed my Zebra Isopod?
The main diet of decaying leaves and rotting wood should always be available. Offer fresh vegetables, fruit or a little protein occasionally, and remove any uneaten fresh food after a day or two to prevent mould. Calcium sources like cuttlebone should also be always present.216
What does a Zebra Isopod eat, and what should it never eat?
Zebra isopods eat decaying hardwood leaves, rotting wood, and occasional vegetables, fruit, and protein like fish flake or dried shrimp. Always provide calcium. For foods to avoid, it is best to ask a good breeder or an exotic-pet vet, as this is not covered in the available information.216
How much space does a Zebra Isopod need?
A colony needs a terrarium of at least 5 gallons (18, 20 litres) with a deep substrate of organic topsoil, flake soil, and white-rotted hardwood, topped with leaf litter and cork bark hides. This gives them room to explore and thrive.267
What temperature, light or water does a Zebra Isopod need?
Keep them at room temperature between 18 and 25°C with moderate humidity and good airflow. Provide a moisture gradient with one damp area and the rest drier. They do not need special lighting and prefer a drier Mediterranean setup.267
How often should I clean a Zebra Isopod's home?
Remove uneaten fresh food after a day or two to prevent mould. The substrate and leaf litter are naturally cleaned by the isopods themselves. For deeper cleaning schedules, it is best to ask a good breeder or an exotic-pet vet.26
Can a Zebra Isopod live with others?
Yes, they are social and should be kept in groups of at least 10 to 20 to thrive. They are not aggressive and can be housed with other peaceful invertebrates, and they are harmless to humans and pets.21
How long does a Zebra Isopod live?
Lifespan varies depending on care and environment. For specific information, consult a good breeder or an exotic-pet vet.
Can I handle a Zebra Isopod?
Yes, they are docile, slow-moving, and easy to handle. They do not bite or sting and are safe for gentle observation, especially during their active evening hours.21
