Physical Characteristics

When caring for Electric Blue Crayfish, it’s important to understand their physical characteristics.

At first, it’s easy to mix up Electric Blue Crayfish and lobsters.

In reality, there is no such thing as a freshwater lobster; they belong to the same family, yet they are much smaller and have some extraordinary physical qualities.

These creatures have a tough exoskeleton that they shed multiple times throughout their life as they grow bigger.

At the front of their body is the head, with two black eyes and horns that look like thorns, similar to what you’d see on a small shrimp or big lobster.

From the head, two antennae protrude, helping the crayfish detect smells and taste their food.

These creatures have four pairs of little legs and one substantial pair of claws. The tail is in the back, curved and wide like a lobster.

Inside the tail are small appendages called swimmerets, which help the crayfish move through the water.

The most recognizable feature of Electric Blue Crayfish is its color – a bright cobalt blue, often with darker spots and white sections on the underbelly.

Although other colors and patterns can be seen in the wild, the blue ones are the ones you’re most likely to find in aquariums.

It can be tricky to tell the difference between males and females, as the variations are minor. Generally, males have straighter tails that are longer when extended.

Breeding And Reproduction


Mating behavior in electric blue crayfish is fascinating to observe.

When ready to breed, a bonded pair will engage in a unique ritual that involves the male depositing a sack of sperm onto the female’s body.

The female then passes her eggs through this sperm for fertilization before carrying them under her tail for approximately one month.

During this time, setting up a separate breeding tank with appropriate conditions and equipment is important for successful reproduction.

Once the tiny crayfish emerge from their eggs after four weeks, parental care becomes crucial.

While the female may initially tend to the babies, aggressive behavior can occur after three days, making it necessary to remove her from the tank.

You can continue feeding them spirulina, baby brine shrimp, and pellets as they grow until they become large enough to join your main tank population.

The molting process is also essential to breeding and raising electric blue crayfish as it indicates healthy growth and development.

Molting occurs when crayfish shed their old exoskeletons and replace them with new ones.

During this phase, provide ample hiding places as they are vulnerable and more susceptible to predation or stress.

With proper breeding setup and parental care, your electric blue crayfish population can thrive while adding vibrant color to your aquarium community.


The electric blue crayfish is a fascinating and unique addition to any aquarium.

With their striking blue coloration and interesting behaviors, they are sure to catch the eye of anyone who sees them.

However, it’s important to remember that these creatures require specific care to thrive.

By providing adequate tank space, appropriate water parameters, and a varied diet, you can ensure your electric blue crayfish has everything it needs for a long and healthy life.

And while they may not be suitable for every type of aquarium or community setup, those who take the time to properly care for these crustaceans will be rewarded with an amazing aquatic pet.
