This is the Cherax a Southern Hemisphere, aquatic Crayfish, for Aquariums.
By Mark on August 4, 2010
Now when I was younger I used to love having a garden pond, but I also used to wonder to myself what other types of aquatic creatures could live in a pond or aquarium. Well has I have left home and moved in to my flat, I have now bought myself an aquarium, as I do not have a private garden. In my aquarium I have placed some fish, but I have learn’t that their are many different species, that can be kept in an aquarium, the most surprising for me is the Cherax, crayfish, but as alot of people who keep crustaceans, it is known as the blue lobster, why?, it is not a lobster it is a crayfish, it is also known as a yabby or mud bug. It is infact a greyish blue, to bright blue, as this species has been breed by many aquarists.
So here we go, here is a bit of information about the blue lobster. The Cherax crayfish is the largest and most widespread genus of fully and partially aquatic crayfish in the Southern Hemisphere. You can find this creature in many areas like lakes, rivers and streams, mainly across most of Australia and New Guinea. Has i said above, this species of Cherax are commonly known as yabbies. But now a days you can find this species in many countries like Great Britian or America, it is the only species of crayfish that is allowed to be sold in Great Britain and this is for aquarium hobbies. Going back to the Australian Cherx, the most common and widely distributed species in Australia is the common yabby, known as the Cherax destructor. It is probably known as a destructor as it will eat pretty much anything it finds, from dead or alive small fish, plants, pellets and other fish food. It is generally found in lowland rivers and streams, lakes, swamps and impoundments at low to medium altitude, largely within the Murray-Darling Basin. Common yabbies are found in many ephemeral waterways, and can survive dry conditions for long periods of time (at least several years) by aestivating (lying dormant) in burrows sunk deep into muddy creek and swamp beds.
This crayfish is a handy fish to keep as it will eat lots of dead matter on the ground and that will help to keep the aquarium clean. But do be aware this creature does like to investigate and as I have learn’t it can be found crawling out of your aquarium, so you must have a strong lid on, to keep it inside. But if it does get out, the chances are as long as you see it, quite quickly, it can survive for a while out of water. So if you are fed up of losing your filter feeding shrimp, like i keep doing, this is probably the next best crustacean to keep, but do remember it can pinch.
