Blue Lobster (Cherax quadricarinatus)

Other Names: Red Claw Crayfish, Freshwater Blue Lobster

How hard are they to keep?
Blue Lobsters are relatively easy to care for, making them a good choice for aquarists with some experience in keeping crustaceans. They require a well-maintained tank with plenty of hiding spots and stable water conditions.

What is its maximum size?
Blue Lobsters can grow up to 12 inches (30 cm) in length, though they typically stay around 6-8 inches (15-20 cm) in home aquariums.

Where are they from?
These freshwater crayfish are native to Australia, particularly found in the rivers and lakes of Queensland and the Northern Territory.

How many can I keep?
Blue Lobsters are territorial and best kept individually unless you have a very large tank with plenty of hiding places. Keeping multiple together can lead to aggression, especially in confined spaces.

How compatible are they with other fish?
They are semi-aggressive and will eat smaller fish or slow-moving tank mates if given the opportunity. It’s best to house them with fast-moving fish or species that stay near the surface. Avoid keeping them with bottom dwellers.

What are the ideal water conditions?
Blue Lobsters thrive in freshwater tanks with a temperature range of 75-82°F (24-28°C) and a pH between 6.5-7.5. They prefer a well-oxygenated tank with hiding spots like caves or PVC pipes. The Blue Lobsters for sale at Friendly Fish have been climatized to our local water conditions.

How do you tell the difference between male and female?
Males tend to have larger, more pronounced claws, while females have a broader tail section to carry eggs.
