🪲 Isopod Care Guide
Isopods are fascinating little cleanup crew members and, with the right setup, are surprisingly easy to keep and breed. While different species can have very different preferences, the basic care requirements are similar for most commonly kept isopods.
Always check the individual care requirements for your particular species, especially with tropical and specialty Cubaris species.
🪲 Why Keep Isopods?
Isopods aren't just a fantastic addition to bioactive enclosures — they make wonderful pets all on their own! 🥰
They're fascinating to watch, easy to care for and a great way for kids and adults alike to learn about nature, life cycles and responsible animal care.
With so many different species, colours, patterns and sizes available, isopods have also become highly collectible. 🌈🪲 From common beginner-friendly varieties to rare and highly sought-after specialty species, building a collection can be incredibly rewarding.
You can start with a single colony and, before you know it, find yourself wanting to collect them all! 😍
Easy to keep • Educational • Fascinating • Collectible • Great for kids & adults
🏠 Housing
Isopods can be kept in plastic tubs, terrariums or other secure enclosures with good ventilation.
For a new colony of approximately 8–12 isopods, a container around shoebox size is a great starting point. As your colony grows, you can move them into a larger enclosure.
Your enclosure should provide:
- 🌿 2–4 inches of suitable substrate
- 🍂 Plenty of leaf litter
- 🪵 Decaying hardwood
- 🪨 Cork bark and other hides
- 🌱 Moss or other natural cover
- 💨 Good ventilation
Isopods spend much of their time underneath leaves, wood and other natural materials, so providing plenty of cover helps them feel secure and gives them places to molt, reproduce and explore.
💧 Do I need a drainage layer?
A drainage layer isn't necessary for most basic isopod setups.
It can be useful in larger or very humid enclosures because it allows excess water to collect below the substrate rather than saturating it. However, a properly maintained moisture gradient is usually all that's needed for a healthy colony.
🍂 Feeding
Isopods are detritivores, meaning they naturally feed on decaying plant material and other organic matter.
Their most important food source should always be:
🍂 Leaf litter + 🪵 decaying hardwood
Keep plenty of both available at all times.
You can supplement their diet with small amounts of:
- 🥕 Carrot
- 🥒 Cucumber
- 🍎 Apple
- 🥬 Other suitable vegetables
- 🐟 Fish flakes or other protein sources
- 🦐 Shrimp-based foods
- 🐝 Bee pollen
Protein is particularly useful for growing colonies and breeding adults, but don't overfeed.
🦴 Calcium
Isopods need calcium to develop and maintain their exoskeleton.
Provide a calcium source such as:
- Cuttlebone
- Crushed eggshell
- Calcium carbonate
- Natural limestone
A small amount should be available to the colony at all times.
Remove fresh foods once they begin to spoil rather than allowing them to sit and mold.
🌡️ Temperature & Moisture
Most commonly kept isopods do well around:
🌡️ 20–26°C (68–78°F)
Some species can tolerate warmer temperatures, while others are much more sensitive to heat. Always check the specific requirements for your species.
💧 Moisture is more important than simply measuring humidity
Rather than trying to keep the entire enclosure equally wet, create a moisture gradient.
One side should remain moist while the opposite side is allowed to stay considerably drier.
This allows your isopods to choose the microclimate they need.
🌿 The Moist Retreat
A section of damp sphagnum moss is an excellent addition to most setups.
Place it in one corner or along one side of the enclosure and keep it consistently damp—not soaking wet.
This gives your isopods a reliable humid retreat, particularly when they are molting.
Never allow the entire enclosure to become waterlogged.
Good ventilation is equally important. Warm, stagnant and overly wet conditions can lead to mold and pest problems.
🐣 Breeding & Colony Growth
Once established, many isopod species will reproduce readily under stable conditions.
Providing:
- 🍂 Plenty of leaf litter
- 🪵 Decaying wood
- 💧 A moisture gradient
- 🌡️ Stable temperatures
- 🦴 Adequate calcium
- 🥚 Occasional protein
- 🪵 Plenty of hiding places
will give your colony the best chance of thriving.
How quickly will they reproduce?
This varies considerably between species.
Some species can establish a large colony relatively quickly, while specialty and tropical species may reproduce much more slowly.
Don't be discouraged if you don't see babies immediately. A new colony often needs time to settle in and become established.
🍄 Mold & Pest Prevention
A small amount of mold is not necessarily a problem in an isopod enclosure. In a healthy bioactive setup, springtails and other microorganisms will often help break it down.
However, persistent or excessive mold usually means something needs adjusting.
🍎 Are you overfeeding?
Large amounts of uneaten fresh food can quickly become moldy and attract unwanted pests.
Feed small amounts and remove anything that isn't being eaten.
💨 Does the enclosure have enough ventilation?
Poor airflow combined with excessive moisture is one of the most common causes of mold problems.
Make sure your enclosure has adequate ventilation while still maintaining the moisture level your particular species requires.
💧 Is the substrate too wet?
Your substrate should be moist, not saturated.
There should not be standing water throughout the enclosure.
If you're constantly dealing with mold, fungus gnats or excessive mites, reassess your:
💧 Moisture + 💨 Ventilation + 🍎 Feeding
These three factors are usually where the problem starts.
🦠 Springtails — Your Best Friend
Adding springtails to an isopod enclosure is highly recommended.
Springtails help consume mold, fungi and decaying organic material, making them an excellent companion cleanup crew.
They won't eliminate every pest problem, but they can help keep mold under control and contribute to a healthier bioactive environment.
⭐ The Isopod Care Formula
If you remember nothing else, remember this:
🍂 Leaf litter + 🪵 Decaying wood + 💧 Moisture gradient + 🦴 Calcium + 💨 Ventilation = Happy Isopods!
And remember — every species is a little different. Some love it humid and tropical, while others prefer a considerably drier environment.
When in doubt, check the care requirements for the specific species you're keeping.
🪲 From our cultures to your enclosure
We want your new colony to thrive, not just survive! Give them a deep supply of natural food, plenty of hiding places, a reliable moist retreat and good airflow, and you'll be well on your way to building a healthy colony.
Happy Pod Keeping! 🪲🌿
Care requirements can vary by species. Always research the specific needs of your isopod before making changes to its enclosure.
