Blue lobsters, also known as Procambarus alleni, are incredibly rare, with a one-in-two-million chance of occurrence. They are found in various parts of the world, including Australia, and even in some freshwater areas. These lobsters are known for their brilliant blue colour, but they can also be white, red, or brown, especially in the wild. While there is no scientific evidence, some believe that blue lobsters are sweeter than regular lobsters. They are opportunistic omnivores and use their strong claws to feed on mollusks, fish, and variations of sea algae.

What You'll Learn

Blue lobsters are omnivores
Blue lobsters, also known as Procambarus alleni, are omnivores. They are known to be opportunistic feeders, meaning they will eat just about anything they can get their claws on. In the wild, blue lobsters use their strong claws to feed on mollusks, small fish, sea urchins, crabs, sea stars, and variations of sea algae. They are also known to engage in cannibalism, especially when young.
In captivity, blue lobsters are not too fussy about water quality or food, making them a good option for beginners interested in breeding crayfish. They will eat live plants kept in their tank, dead and dying fish, snails, blanched vegetables, and sinking pellets and wafers. It is important to note that blue lobsters are not plant-safe and will eat, cut, and uproot any plants in their tank.
The diet of blue lobsters in captivity may vary depending on their living conditions and the availability of food sources. It is recommended to provide them with a sufficient hiding place, especially when they are molting, as they are extremely susceptible to attacks from other crayfish and fish during this time. Additionally, ensuring a plentiful source of calcium can help prevent incomplete molts.
While blue lobsters are known to be aggressive feeders, their behaviour can also be influenced by their environment and the presence of other species. In community tanks, blue lobsters may exhibit aggressive behaviour, size, and feeding habits, making them challenging to keep with other species.

They eat mollusks
Australian blue lobsters, also known as Procambarus alleni, are an incredibly rare species of lobster. They are known for their striking blue colour, which has made them popular in the aquarium trade. These lobsters are typically found in freshwater areas, and their diet consists of a variety of prey, including mollusks.
Blue lobsters are considered opportunistic feeders, and their diet includes small fish, sea urchins, crabs, and sea stars. However, their primary food source is mollusks. These lobsters use their strong, specialized claws to tear and crush their prey. The sharp cutter claw helps tear the prey, while the larger and dented crusher claw is used for crushing it into smaller pieces.
The diet of blue lobsters in captivity may differ slightly from those in the wild. In aquariums, they are known to be omnivores and will eat a variety of foods, including sinking pellets and wafers. While they are not too fussy about water quality, they require a sufficient hiding place when molting, as they become vulnerable to attacks from other crayfish and fish during this time.
In the wild, blue lobsters are known to feed on mollusks, which are a significant part of their diet. They use their strong claws to catch and tear their prey, including various types of mollusks found in their natural habitat. The exact species of mollusks consumed may vary depending on the specific region and availability.
Overall, the diet of Australian blue lobsters consists of a variety of prey, with mollusks being a preferred food source. Their opportunistic feeding behaviour and strong claws allow them to access and consume a diverse range of prey, including various types of mollusks.

They eat fish
Australian blue lobsters, also known as Procambarus alleni, are an omnivorous species. They are known to eat fish, as well as other aquatic animals and plants. In the wild, blue lobsters use their strong, sharp claws to catch and tear apart prey, which can include small fish. They have two types of claws: a sharp cutter claw for tearing prey and a crusher claw for crushing food.
Blue lobsters are opportunistic feeders, meaning they will eat whatever they can get their claws on. In captivity, they have been observed to eat live plants, dead and dying fish, snails, and blanched vegetables. They are not plant-safe and will cut, eat, and uproot any plants in their tank.
Blue lobsters are also known to exhibit cannibalistic behavior, particularly when young. They are highly responsive, and some have observed that they seem to "beg" for food when they see people walk by their tank.
In terms of diet, blue lobsters are not fussy and are thus considered an excellent species for beginners interested in breeding crayfish. They are hardy and adaptable, able to thrive in various water conditions.

They eat sea algae
Blue lobsters, also known as Procambarus alleni, are a type of lobster that is native to Australia and other parts of the world. They are known for their distinctive blue colouration, which has made them popular in the aquarium trade. While they are considered rare, there have been reports of fishermen catching them off the coast of Maine, US, in recent years.
Like regular lobsters, blue lobsters are omnivores and opportunistic feeders. This means they will eat a variety of things, including small fish, sea urchins, crabs, sea stars, and sea algae. They have two specialised claws that help them catch and tear prey, as well as crush their food.
One of their favourite foods is sea algae. Sea algae is a general term for a diverse group of photosynthetic, marine organisms that include multicellular forms, such as seaweed, and microscopic forms, such as phytoplankton. Sea algae are typically found in coastal areas and provide an important source of nutrients for many marine creatures, including blue lobsters.
Blue lobsters can be found foraging for sea algae in rocky and coral reefs, where they use their strong claws to tear and crush the algae into manageable pieces. They have poor eyesight, but their sense of smell and taste is heightened, which helps them locate and identify edible sea algae.
In addition to sea algae, blue lobsters may also eat other types of plant matter, small fish, and mollusks. However, their diet can vary depending on the availability of food sources in their habitat.

They eat live plants
Blue lobsters, also known as Procambarus alleni, are an omnivorous species. They are known to eat a variety of things, including live plants. In fact, they are not considered plant-safe and will eat, cut, and uproot any plants in their tank.
Blue lobsters are typically found in freshwater areas and are known for their bright blue colour. They are considered opportunistic feeders, meaning they will eat just about anything they can get their claws on. While they are often sold in aquariums, their aggressive behaviour, size, and feeding habits make them suitable for a single-species setup.
In the wild, blue lobsters use their strong, specialised claws to feed on mollusks, small fish, and variations of sea algae. They have a sharp cutter claw that enables them to tear their prey and a crusher claw that is used for crushing their food. These claws are also important for defence and attack.
When it comes to live plants, blue lobsters have been observed to consume, cut, and uproot them. This behaviour is not limited to a specific type of plant, as they have been known to eat a variety of plant species. While some people choose to provide blue lobsters with cheap plants that can be replaced monthly, it is important to note that blue lobsters will not leave plants alone in their tank.

Frequently asked questions
Australian blue lobsters, or Procambarus alleni, are omnivores and opportunistic feeders. They will eat anything they can get their claws on, including live plants, dead and dying fish, snails, blanched vegetables, and sinking pellets and wafers.
Blue lobsters are very aggressive and territorial, making it nearly impossible to keep them in a community tank. They will eat, cut, and uproot plants in their tank.
Blue lobsters require a sufficient amount of calcium in their diet to prevent incomplete molts. They should also be provided with a hiding place when they are molting or have recently molted, as they are susceptible to attacks from other crayfish and fish during this time.
