The Common Yabby is an Australian Freshwater Crustacean where they are very common in slow-flowing or stationary bodies of water such as lagoons and back-waters. There are three sub-species: Cherax Destructor Destructor, Cherax destructor Albidus and Cherax Destructor Rotundus. An all-blue variation, called the Blue Pearl Lobster is perhaps the most common in home aquariums.
The housing should be treated exactly like Cherax Destructor. They are hardy and quite comfortable in cold or tropical water. They will dig and eat plants so not recommended for display or plant tanks. They can also be territorial so provide plenty of hides.
As yabbies grow they shed their shell and at this time can be vulnerable and eaten by other tank inhabitants. If for any reason yabbies lose a limb, these will be regrown over the next few moults. As with other invertebrates, they are sensitive to copper treatments. Yabbies are also escape artist so a cover glass is needed.
