Male or Female

[Human Shrimp]

In my 5.5 gal I have 1 male 5 females. At least I hope it's like that. The shrimp I belief to be male has the body shape of a male (slimmer, tail raised when resting, and curved underneath) but I noticed something yellow on his back, it looks like a saddle. I really want them to breed, can anyone confirm its gender?

Here's a better photo of it resting:

I still have a difficult time sexing shrimp under 4 months or so, but to me, that looks to be male. That underbelly appears straight when males are young but as they age, it takes on a fish-like shape. Kinda like a slight S-curve shape to the belly. Females are rounder bellied and look more "stout" in general. Not always bigger, but beefier. Sometimes that 2nd scale will overlapp scales 1 and 3, but not always easy to see this in females that haven't carried. I never could go by that antenna trick to sex them. I've seen males with what looked to be short antennas up top.

Hey everyone

 

Hope its all going well! I'm new to the hobby, and I would like to have the same help here.

I have had my Shrimpies for about a month now, and I have been searching to try and identify if they are male or female, but I'm not 100% sure 😐

 

I'm hoping that someone here can help a man out here.
I'll post a pic and what I think they are, but please correct me if I'm wrong!
