A pair of blue Dwarf Crayfish (Cambarellus Shufeldtii?) together?

[muser]

Hi fellow crayfish keepers,

I'm new to dwarf crayfish keeping, and would like to seek your kind advice.
I'm currently keeping a pair of dwarf blue crayfish in my desktop 30cm tank.

They are really cute and tiny.

May I know if it's better to keep them separately after all?
(so that the female can berry better etc?)

Below are some pics, including a single baby that I found during water change (never saw its mom berry, which is why I am asking for advice )

Much thanks in advance m _ _ m

Zoom in on the tiny baby...

Are these really blue Dwarfs? They look like the normal babies of P.clarkii to me. The babies I had were blue at their younger stage.
