Blue Crayfish species

[enwelz]

Could someone fill me in on what species this is? I have one but I don't know what it is exactly. And can anyone venture a guess at how large it could get if it is well fed in a 55-gallon, it will be moved to something much larger in the future.

To me, they look like yabbies or marrons!

They do resemble a Cherax species....but I can't be sure from the photo.

It's a Cherax Quadricarinatus. That one looks female to me because it doesn't have the red pads on the outside of its big claws. I've got a male.
Edit: Oops, forgot to finish....they get big, up to a foot but normally around 9" or a little more in an aquarium. I got mine at about 6" 6 months ago, he's molted twice and is every bit of 9" now. They're said to do better with other quads, not as aggressive as some crays. Mine lives with 5 Gouramis and a female Convict, he never bothers the fish but don't put fish in with a cray you're not willing to lose.

yup definitely Cherax quadricarinatus or blue lobster or Australian yabbies. My females just had lots of babies... to many to count... so it’s selling to the pet stores or the local Chinese buffet when they’re ready!!!
