Marble crayfish and Dwarf Cajun crayfish?

[katelyn7014]

Would they be okay together in a 40 gallon tank? Just curious since I read that for crayfish they are pretty peaceful in community tanks... Curious if they would be okay with each other too? If anyone knows that would be great!

I have 1 marbled and a cobalt blue in a 55, my cobalt blue killed all his tank mates in my 20, but they haven't had any issues in the 55. Know that probably doesn't help, but you don't have to worry about the marbled, unless she's berried up then she'll be aggressive at her "territory" at least in my experience with them anyways

If it is a 20L are larger they should be fine.
