Rubber Ducky Isopods: An Overview
Rubber Ducky isopods are given the name due to their resemblance to the popular rubber duck toy in color and facial features. They are originally a part of the crustacean species. They are native to Asia’s highly humid limestone caves, especially in Thailand. Therefore, a highly humid environment is necessary for them to survive.
Like other woodlice, rubber ducky isopods can roll into a tight ball as a defense mechanism, which helps shield them from predators.
Although they are the most popular isopods globally, they are rare and unique. These exotic creatures are especially attracted to vegetables like cucumbers and sweet potatoes. Despite loving vegetables, they are essentially detritivores and play a crucial role in breaking down decaying organic matter, which supports the overall health of their environment.
Their non-aggressive temperament and small size make them the perfect beginner-friendly pet isopods.
Rubber Ducky Isopods: Basic Care
Rubber Ducky isopods need to have a highly humid environment to survive. So, you have to always keep the tank warm and humid. The temperature inside the tank should be between 25 and 28 degrees Celsius.
You should also maintain the humidity level between 75% to 90%. Regular misting is important to maintain proper moisture levels and support healthy molting. It is important to provide shelter in the tank, such as logs, rocks, or moss, and to create multiple hiding spots to give Rubber Ducky isopods safe retreats and ensure their well-being. The Rubber Ducky isopods usually start breeding within a few weeks. Specifically, the female isopods start breeding at three months old. Stable conditions are necessary for successful breeding and the long-term health of the colony.
Rubber Ducky Isopods: Feeding
The Rubber Ducky isopods need to have a protein and calcium-rich diet. Decaying wood and rotting wood are important food sources and substrates for rubber ducky isopods, providing essential nutrients and mimicking their natural environment. They require all the essential nutrients to survive well in a new environment, including a variety of food sources such as organic material like dead leaves and plant debris. As this species is slower-growing, you must feed them occasionally to aid their growth.
Calcium sources such as crushed eggshells and garden lime are essential for their diet, helping to build strong exoskeletons and maintain overall health.
You can use the following food items to feed them, including fish flakes as a protein supplement.
Calcium
Rubber Ducky isopods are naturally present in limestone caves and similar calcium-rich areas, where calcium carbonate is a key component of their natural substrate.
They require a significant amount of calcium to grow and reproduce, as calcium sources help build strong exoskeletons and support healthy exoskeletons in isopods.
The best calcium-rich food items you can give these isopods are the following.
Cuttlebone
Powdered eggshells
Limestone
Sea corrals
Protein
Protein is crucial to the breeding health of the isopods. Following are the best food options for these isopods regarding protein.
Shrimp shells
Insects like crickets
Shrimp
fish flake
Organic yeast
Small pests and their eggs, as isopods may also feed on these, helping control pests in their environment
Leaf Litter
Leaf litter is unavoidable for them. It is essential to provide them with pesticide-free leaf litter. Leaf litter is pretty affordable and easily available. You can give a lot of leaf litter to the isopods every time you feed them.
The most suitable leaf options for them are as follows.
Oak leaves
Magnolia leaves
Cannabis leaves
Seed blends
Fungi and plants present in the substrate help break down organic matter, contributing to nutrient cycling and providing additional food sources for isopods.
Adding sea almond leaves to the enclosure can help maintain a low pH in the substrate, which is beneficial for the breeding and health of rubber ducky isopods.
Rubber Ducky isopods are detritivores. In other words, they are interested in eating decaying matter. So, keeping some decaying fruits, softwood, etc., in the enclosure is also advisable.
Rubber Ducky Isopods: Appearance and Behaviour
Appearance
Rubber Ducky isopods are the most popular for their appearance. Their unique facial structure makes them look similar to the rubber duck toy. Their heads also have a similar yellow color, making them further identical to the real rubber ducks.
They usually grow up to 1.5 cm. On the other hand, certain variants can grow up to two centimeters. They are available in shades of brown and yellow.
Their body is divided into seven segments. Each segment of this isopod has a separate pair of legs. Among the multiple legs, two are specialized for burrowing. They use these burrowing legs to dig into the substrate for safety and can reach depths of up to six inches, which allows them to hide and shelter as part of their natural behavior.
Rubber Ducky isopods have a hard exoskeleton that provides protection and support. This exoskeleton helps defend them against predators and environmental extremes, and plays a crucial role during the molting process as they grow.
They have two antennae on their heads. These antennas help them with navigation. On both these antennas, there are small projections called Cerci. Cerci is used as a sensory organ by these isopods.
Behavior
Rubber Ducky isopods are known for their calm temperament. This calm behavior is one of the primary reasons for its popularity. They don’t mind interacting with other pets and animals. But keeping the small pets separate from them is advisable to avoid conflict.
They usually prefer to remain in the tanks where they get enough food. So, they typically do not try to escape from the tanks. These isopods interact with humans, too.
But the human interaction may take some time. However, they interact with the keepers and other animals once comfortable with their surroundings.
These isopods gradually get comfortable with their surroundings. They develop a playful temperament once they feel comfortable.
Many of these isopods even let the keepers take them in their hands and play. They usually spend several minutes in the keeper’s hands.
Rubber duckies are easy to care for and highly adaptable, making them a favorite among keepers. They thrive in well-maintained environments with proper temperature, humidity, and ventilation. Stable populations of rubber ducky isopods depend on consistent care and suitable environmental conditions.
Classification
Isopods are part of the subphylum Crustacea, which means they are closely related to familiar aquatic animals like crabs and lobsters. With over 10,000 isopod species identified worldwide, isopods display an incredible variety of forms and behaviors. The rubber ducky isopod, known scientifically as Cubaris sp., is a particularly sought-after species among collectors and hobbyists. As a classic example of cubaris species, rubber ducky isopods are prized for their rarity and unique appearance, but they are more challenging to breed and care for compared to hardy isopod species like Porcellio laevis, which is well-known for its robustness and ease of care. Native to Thailand, this isopod is recognized for its small size and distinctive yellow and brown coloring. Understanding the classification of isopods, especially the Cubaris sp. “Rubber Ducky,” is essential for anyone interested in their care. Knowing their origins and natural environment helps enthusiasts provide the right conditions, such as high humidity and the proper substrate, to keep these fascinating creatures healthy and thriving.
Rubber Ducky Isopods: Habitat
The habitat you create for a Rubber Ducky isopod must have the following features.
The tank should always be warm and humid. Maintaining proper moisture levels is crucial for isopod health, as it supports molting and overall well-being. Including sphagnum moss in the substrate helps retain moisture and provides a supportive environment for healthy molting. Sphagnum moss helps keep the habitat moist and hydrated.
Provide plenty of hiding spots using bark, leaf litter, or cork to mimic their natural environment and offer secure retreats.
Using soil as part of the substrate mix helps replicate their natural habitat by retaining moisture and supplying essential minerals.
Consider a bioactive setup in your vivarium, incorporating live plants and bioactive custodians such as springtails and other invertebrates. This creates a self-sustaining ecosystem and enhances habitat stability.
The water should always maintain a pH level between 8.0 and 8.5.
The hardness of the water inside the tank should be between 10° and 15° DH.
The tanks need to have a good amount of light. You can use terrarium lights as light sources.
The lights should not shine directly on the isopods.
Rubber Ducky Isopods: Substrate Mix
These isopods need to have a rich substrate mix.
As they dig about six inches deep, you must fill the substrate mix at a good thickness in the tank.
The essential things to add to the substrate mix are limestone, calcium carbonate, decaying wood, rotting wood, organic matter, decaying matter, leaf litter, etc. Decaying wood and rotting wood provide nutrition and support burrowing, while calcium carbonate is necessary for exoskeleton development. Including organic matter helps support nutrient cycling.
The substrate mix should have peat moss and coco coir.
