Welcome to the forums!

I know of an Australian crayfish that's called a "zebra crayfish". Obviously that wouldn't be native to your area, so I'm not sure if that's a matter of semantics or the breeder breeds Australian species.

If indeed it is an Australian crayfish, which somebody here can hopefully confirm or deny (pics would help), then be sure you do not introduce a North American crayfish into the same tank as the Australian. North American crayfish can be carriers of the "crayfish pestilence", to which they are immune but other crayfish, such as the Australian variety, are not.

Like I said, some pics of the crayfish would help in identification. And again, welcome!

I would say that as long as the tank is large enough (10 gallons per cray) and the filtration is sufficient, you would be okay to keep a pair of male/female in there. Just make absolutely sure you never put a North American cray in there. Don't even use the same buckets to change water from tanks that hold North American crays.

Yeah you'd be fine with a pair in a 50 gallon. Can't wait to see pics!

To post a pic, just upload the picture to an image hosting service (like imgur: http://www.imgur.com) and then when making a new post. click the "Img" button above the big white response box. Two little boxes will appear that say [ 'img' ]. In between those boxes place the URL of your image.

To sex crayfish, just look at the bottom of the crayfish like this:

I would love to see pictures of this cray also!

In my experience, most cray species prefer the darkness. Maybe the guy told you that to get you to buy it. Maybe she will eventually come out more
