Australian Cobalt Blue Giant Crayfish (Cherax cainii)

                                                                                     This species is also known as the blue marron. This species grows to 15 inches and can weigh up to five pounds. They are an intense dark blue. The downside is that this is a difficult species to keep long term. They require very high quality water (even low levels of ammonia will kill them) and should be kept in the 70s. They will start dying when temperature exceeds 80°F. Besides the water quality they do best with a small amount of sea salt ( we use one heaping teaspoon per 4 gallons) and with live blackworms and fish as a component of the diet. These are for serious hobbyists only.

Redclaw crayfish (Cherax quadricarinatus)

                                                                              Redclaws are a large and impressive crayfish that can be kept in small groups. They can be active during the day and make a great display. Jumbo redclaw males can reach 14 icnhes and weigh over a pound.

Pearl Lobster (Cherax destructor albidus)

                                                                                   This is the typical form of the pearl lobster, not blue, but still very attractive and showing lots of variation. The leg joints are a bright orange red.

Blue Moon Lobster (cherax sp.)

Cherax sp. (Blue Moon Lobster)                                                               This is the spectacular blue morph of Cherax albidus, previously known as a blue Cherax destructor. In our opinion it is one of the most beautiful and most easily kept of crayfish. These grow fast and end up with the proportions of Maine lobsters. Males can reach 8 inches and weight up to a half pound. Lifespan in captivity is 5-6 years.
