Can you see that long wedge of yellow inside that shrimp? That's the 'saddle', ovaries for the female shrimp. Given the colour on the other shrimp, I'd bet that one is also female. Usually, cherry males are thinner and less colourful than the females, and wont have saddles.
That's also SOME BARGAIN you got on that Chi. Nice deal!
Oooh, yeah, the other one has a long yellow wedge inside of it too so you're probably right. I have two females! Guess I'll need to find some males, hah! I was so happy I found a Chi on Craigslist though a bit wary of where the meet-up was (a Starbucks in the shady part of downtown LA). I sent my boyfriend instead
