Wow that is realy a different crayfish.How come you think they would be hard to keep Yucca? The only problem that seams obvius to me would maybe be sensitivity to high temperatures .

What have worked best for me with dwarf crays is giving the pregnant females their own little tanks with lots of plants it also makes a good nursery for the fry.It does not even have be any filter with such a small bio load.Or keeping them in pairs in small tanks and remowing the male
after spawning.

Sterility of males would be the last thing I would be concerned about. By the way...I know *for a fact* that your males are not sterile, as the females would not be carrying around unfertilized eggs for any appreciable amount of time. Plus, those eggs would turn a different color (different from th...

Inbreeding only gives a individuum a higher chance of having some defects in both copies of its genes. If one selects for these genes to be ok, when inbreed...
