I'm not sure if this is the correct area to post this if not please move it.
I am relatively new to keeping shrimp but I am experienced in raising and breeding both freshwater and saltwater fish. I recently purchased a quantity of "Bloody Mary" shrimp at an auction and I noticed that there are a few shrimp that are significantly darker than the others. From the picture would the shrimp in the center be "black" or just a real dark red? Also would this be considered to be a desirable trait?
Thank you for your help/responses
