Are they Bloody Mary male?
Each picture is a different shrimp. Any of them is male?
They are so small compare to the female. They are just 1/2 of the female. For the big female, they are just 1/3 of the big female.
If they are males, do they have any issue to sex with the female that is double or triple his size?
I saw my female ones have saddle for like 3 weeks already. But I can't find any of them berried.
All of them were at the same size when I got them, but now some of the female are much bigger than thw one in the picture.
