White Cray, help with ID
I was at my LFS today and they had two small white crayfish. Of course I could not resist, but they had no clue what they were. As luck would have it one is male, the other is female. so if they live, I might get lucky!
Anyway, any hep with ID would be appreciated. I need to know if these are just juvies, or if these will grow into monsters:
Right now they are just 2".

Mustafa is correct, they could be clarki. The only way to tell is to look at the differences in the male's gonopods and they are pretty easy to distinguish if you really look at them.
Both clarki and alleni are very good at escaping and neither are a dwarf species, so it's best to make sure your tank is secure.
If you breed too early the female is far more likely to eat the berry because it isn't fertile. Of course, with the white alleni that often happens later as well. The white alleni doesn't seem to be a very prolific breed. That is perhaps because they are albinos or just a thing with the whites. At any rate, I wish I didn't have to be breeding these for the aquariam trade when I have other ones I want to work on, but they still aren't doing very well so I am breeding them instead of working on newer species to help them get started.
I do wish you well and hope you get a line of them going!

I think they would have to breed true. Albinos have no pigment and gene is ressesive.
I'll give it a shot if I can keep them alive. I also just won an auction for 4 cobalt blue alleni. As it turns out I won the draw and I get them free, including shipping. So now I have to figure out where to put them. Looks like the cajuns are moving to the 20 gallon tanks.

Was provided by michiganmale248 as hows some really good pics on how to tell by the gonopods. I am a little confused now on how to find them. Do they lay flat agains the wlaking legs and you use the toothpic to separate them?
There is also some info that most crays males are only fertile every other molt. Is that so?
