Rod, I think this crab is a blank slate for color patterns! Just having black on the shell means the opportunity for color mutations and selective breeding is there. It's very exciting!
AND due to the fact crabs have vast amount of babies at once, it is a dream for selective breeders! Shrimping basics have to serve us well!
phree, from what I read they are opportunistic, so would have to be kept with shrimp culls as they would probably eat them if they could catch them.
Now after all that, I STILL can't find anything on their breeding.
