Cubaris Isopods Care

Cubaris enjoy damper, mild temperatures of 70-80°F (21-27°C), and increased humidity environments of around 60%. Their diet includes decomposing wood, sliced vegetables, and crushed limestone as well as cuttlebones and crushed eggshells. Provide a transparent plastic container of at least 10 gallons for 10-15 isopods. As a substrate use decomposing wood mulch, rotting cork bark, an abundance of sphagnum peat moss, limestones, and natural leaf litter.
This post will concentrate on those components of maintenance that will allow you to keep happy, robust Cubaris in your home.


They will only reach a maximum size of 2cm or 0.79 inches, making them acceptable for most terrariums.  Rubber Ducky isopods are slow breeders that take a few months to achieve full size. They aren’t very fast at reproducing once they’ve reached adulthood.


Just like other isopods found in the environment, the Cubaris Isopods are known to have a lifespan of around 3 to 5 years, depending on the care being provided.  The overall lifespan of your isopods is based on various factors, most of which are associated with the environment they are being kept in and diet. 


The thing that makes these creatures so rare is how hard it can get to breed them in a single group. Because they take a long time to mature,
There isn’t much documented about the Isopod because some varieties  were discovered only a few years ago. to make them healty you must follow some important rules.


Isopods can be kept in a diverse range of containers. You may start small if you just want to create your colony .You can even put them in a terrarium or vivarium with a species already in it. Transparent containers will be the best option only if you have enough space in the box and don’t fill in too many isopods at a time. Here is a rough guide to the size of a container about the number of bugs you keep:

  • 20 liters for 10-25 bugs
  • 30 liters for 25-50 bugs
  • 30 to 40 liters for 50-65 bugs
  • 50 liters for 100 or more bugs

Because of the smooth surface, many creatures are unable to reach the sides of an acrylic container. Another option is to keep your Rubber Ducky isopods in a tiny container. We’re not referring to a simple metal tin here; we’re speaking about 1-liter containers. You can create an optimum enclosure for your Isopod by providing it with all the requirements.
Make various ventilation holes.
Begin by laying down your soil and a good covering of leaf litter on top.To generate a humidity gradient, you like to cover 1/3 of the cage with a dense covering of sphagnum moss which is kept damp at all times. Add a chunk of bark, wood, or cork bark after that.


With decomposing wood mulch, rotting cork bark, an abundance of sphagnum peat moss, limestones, and natural leaf litter, a proper living soil focuses on variety and developing a very rich and dynamic medium. These crucial building blocks are needed for preserving these isopods, as well as many other uncommon isopod species, alive and reproducing. The Cubaris Isopods enjoy eating dead organic material, especially decomposing old cork bark, and are an important component of many habitats.

Rubber Ducky Isopods, like all other Isopods, are Crustaceans, which means they are more closely connected to Lobsters and Crabs than to regular soil-dwelling bugs and insects.  The coco fiber and sphagnum moss will enable them to retain the greater degree of humidity they require, while the leaves and wood will be their main source of nutrition. 

Mix soil base with:

  • 10 percent of sphagnum moss
  • 25 percent of coco fiber
  • 10 percent of crushed limestone
  • 15 percent of dried leaves


When it comes to the natural environments of Cubaris species, they prefer to be in the middle of the range.  Even Thailand’s stone tunnels will remain around 21-27 degrees Celsius.

Rubber Ducky isopods prefer that this range is maintained as long as moisture levels are monitored regularly.


Cubaris Isopods species need humidity levels around 60%.
Isopods from the genus Cubaris originate in tropical, high-humidity settings. You gently wet the entire enclosure once or twice daily to ensure a humid climate,


When contrasted with other isopods, this kind of pill insect requires a relatively broad diet. dead leaves are necessary for this species, as they are for most others in this group. It’s it’s important  to include a lot of protein : Decomposing wood, sliced vegetables, and crushed limestone should work.  Your Cubaris Isopods must have consistent and exact calcium, leaf litter, protein supplies, and many other dietary components.

Calcium Supplies

  • Cuttlebone 
  • Emulsified Egg Shells (Powder Form)
  • Limestone 

Protein Supplies

Most Cubaris species, we’ve discovered, prefer a range of protein feeds, and this variety appears to maintain these slower-growing Isopods‘ content and reproduce constantly.

Sources of protein for this species include:

  • Shrimp Pellets 
  • Shrimp Meal 
  • Cricket flour
  • Shrimp Shells 

Pesticide-Free Leaf Litter

When acquiring these designer isopods, it’s critical to note that we don’t compromise on the last necessary diet and environment item, termed leaf litter. Certainly, you can collect leaves outdoors, but only if you are certain they are pesticide-free. Following are the types of leaf litter used as a source of diet for the Isopod:

  • Cannabis Leaves
  • Oak Leaves
  • Magnolia Leaves

    Or take some leaves in the nature but is important to boil them to avoid parasites and little insects invading your colony


Cubaris Rubber Ducky isopods can be difficult to breed. One of the hardest to breed is the Cubaris Rubber Ducky . instead Cubaris Panda King reproduces easier.

Rubber Ducky Isopods are unusual-looking Cubaris isopods that are not suitable for beginners since they demand a precise degree of temperature and relative humidity.

They are more difficult to reproduce than some other isopods and are pickier. However, once their needs are fulfilled, they will thrive just fine.
