Cubaris murina Care Guide

Every living organism is different from others, be it in size, growth, or reproduction rate.

Cubaris murina has a slightly slower or moderate reproduction rate, depending upon the established envelope you have provided for breeding.

Cubaris murina is quite charming and cute in gray color, with two vibrant orange-colored dashes on their right part of the body, also known as pleon.

With time the dashes tend to get darker in color as Cubaris murina gets close to maturity age. 

Cubaris murina is among the shy species from the family of Armadillidae, as they are searching for low grounds always.

They prefer spending time either above or below the soil, depending on the type of soil and other environmental conditions. 

Many hobbyists would have noticed that Cubaris murina aren’t the hardworking isopods, as they tend to always search for soft ground, where they can spend their time and rest up.



Cubaris murina is said to be a medium-sized isopod due to its overall size. These isopods can grow up to 3/8 inches or 0.95 centimeters in size.

If you place a 15 cm uniform ruler, you can easily adjust 15 Cubaris murina isopods on it.

If you are a hobbyist, you would understand that their size doesn’t matter unless you are providing a well-maintained growing environment.

When these isopods fear danger around them, they use their body as the primary cover, curling themselves into soft body shells. 

Every isopod has a special body, which differs it from other isopods in their family. Not every Cubaris murina is able to grow about 1.2 centimeters in length.

It’s the care and patience a hobbyist or a keeper posse in order to look after its isopods.



Like other isopods in their family, Cubaris isopods are also able to enjoy their life for up to a year. Their social environment and behavior play a vital role in their upbringing and overall lifespan.

If treated with care and love, Cubaris murina isopods can live two years or even greater. 

Like other isopods, Cubaris murina is capable of breeding in 14-30 days, depending on their lifestyle and other conditions. Breeding duration or breeding properties doesn’t affect an isopod’s net lifespan.

The environmental conditions directly impact an isopod’s lifespan and character traits. 

isopod’s growth depends on the condition of their living envelope, which depends upon several factors, including humidity, moisture, temperature, and substrate.

It’s best to invest in a well-built envelope for isopods if one is looking for an extended lifespan and healthy growth. 



While breeding Cubaris murina isopods, one has to look after their terrarium and its overall environment.

Though Cubaris murina doesn’t require any special treatment, their offspring start appearing in two to three weeks, making the terrarium overcrowded.

Hence, it’s important to control the entire envelope, keeping it clean from animal wastes and other impurities. 

Secondly, the height of the substrate should be optimized according to the requirement of the Cubaris murina isopod.

Moreover, it gets important to maintain the humidity and saturation of the substrate inside the envelope. 



Like every living organism, isopods also require an ideal growing environment. The setting of the enclosure directly impacts the breeding and other activities of the Cubaris murina isopod.

Talking about the humidity, the rate of humidity should be maintained at around 70% or even more to make Cubaris murina feel at home.

Providing an interactive bio enclosure to young isopods boost their cannibalism rate, impacting the breeding mechanism.

In order to keep the enclosure moist, it’s recommended to perform misting twice a week, keeping the enclosure humid and according to the adaptations of Cubaris murina isopods.  



In nature, Cubaris isopods are found on a calcareous substrate containing an average amount of lime.

As Cubaris murina isopod can thrive in any soil conditions, it’s ideal to provide them with compost topsoil.

Adding coco fiber and leaf litter would certainly improve the quality of the substrate, which is important in creating a natural environment for Cubaris murina isopods. The substrate shouldn’t be oversaturated, creating discomfort for breeding isopods. 

Adding crushed limestone to the enclosure will keep it moist. It is better to create a completely integrated ecosystem that includes at least 10% limestone and Sphagnum Moss and 25% coco fiber and 15% dried leaves combination.

In general, isopods prefer staying surrounded by naturally occurring constitutes that offer an environment close to their natural habitat.

Providing them soft and 100% natural substrate would best fit their needs, encouraging healthy growth and breeding.

The deciduous forest humus offers much organic content to the soil, creating a well-balanced internal environment just for Cubaris murina isopods. 



The family of isopods is resilient to temperature changes around them. Hence, the temperature being one of the most important factors, it’s important to maintain optimum temperature levels to breed Cubaris murina isopods. 

Temperature ranging between 70-85°F (25-33°C) with at least 70-75% humidity is ideal for growing and keeping Cubaris murina isopods.

If you are living in a fairly cool environment, it’s recommended to keep your acrylic tank or terrarium in a spot where it receives ample indirect sunshine.

Indirect or dappled sunshine would keep the acrylic glass warm, benefitting growing isopods that require optimum growth temperatures.

Since it's important to keep your Cubaris Murina's enclosure warm, place it somewhere that receives dappled or indirect light

Organic compost and dead leaves also produce sufficient heat for maintaining the internal environment of terrariums.

Raising Cubaris murina is relatively easy; however, one has to take care of the temperature values and relative humidity levels.

Adding desired substrate type and other additive elements can also increase the overall heat in the tank.

Hence, the temperature of the animal tank or terrarium needs to be maintained throughout the year, irrespective of the external or surrounding temperatures.

Placing an under-tank heater would provide sufficient heat to the tank in cold environments. 



Cubaris murina isopods are adapted to specific humidity levels in their surroundings. Be it any substrate or type of animal tank; the keeper must maintain the humidity inside the tank.

Cubaris murina are crustaceans, and they enjoy rising humidity and moisture levels in their surroundings.

As Cubaris murina grows in temperate and moist regions of the Pacific Ocean, tropical Asia, Mexico, South America, North America, and Australasia, they enjoy humidity levels around 70-75%.

In order to avoid excessive temperature gain, one can drill some holes in the tank to enable cross ventilation. 

The overall growth and reproduction of Cubaris isopods depend upon the temperature, moisture, and humidity content. As hobbyists grow Cubaris in an artificial made environment, they have to take care of all basic parameters.

Handling Cubaris murina isopods is easy. The required humidity percentage can be attained by keeping the acrylic tank, animal pot near the windowpane, or cozy warm spot.

It is said that they breed and eat well where the humidity rate is above 75%.

To create ideal moisture levels, hobbyists can sprinkle a small amount of water on the tank; however, the substrate shouldn’t be oversaturated.
