The first 3 pics, I took a couple weeks after getting them, so perhaps about 1.5 - 2 months old?
This is the larger female early in her pregnancy; she had a lot of eggs and I even noticed some excess on a plant. She's colored up more since this pic.
A comment I'd like to make is that I've seen a few pics "depicting" shrimps mating. The ones I've seen show the male alighted on the back of the female. However, that is not what I observed, so could Red Cherries be different?
What I observed was, while passing by the tank, I noticed a female lying on her side in the open and I thought, "Oh no, she's dying." For after all, shrimp seem to just keel over when dying. Upon closer inspection, I thought I saw a molted exoskeleton on her underside. But it was the male lying on his side too, and they were embraced, face to face. They stayed like that for about 7 more seconds (I have no idea how long the whole thing took, for I happened upon them in progress), then they sprang apart. Then within the next hour or two, I watched the process of eggs descending down into the pleopod area of the newly mated female.
Here's the female with the almost full red coverage.
She's actually carrying eggs in this particular pic but has much less than the larger female. I usually have a tough time seeing her eggs.
I've really come to enjoy the male Red Cherry - almost more than the females! I rather like that he's distinct from the females, so I'll just let the females have the glory with the red. The males are so cool how they "hover swim" like miniature flying horses. Even their hanging legs make them look like they're galloping.
I don't usually see the females swimming around like that; perhaps because the "swimming" is more related to the male's need to search for females?

. Csmike, I don't mind, I use a very old point and shoot style digicam, Nikon 5700. I use the macro feature and try to use natural lighting, be it daylight or the aquarium light, which means I have to use a tripod or a stable surface (sometimes shooting as slow as 1/4 second). A direct flash at times, unfortunately, gives unnatural color because the exoskeleton bounces back a lot of the light (not to mention aquarium reflection if at the wrong angle). Some shrimp come out prettier with direct flash, shows a lot of weird colors (and of course you get sharper pics) but is misleading if you're trying to identify a species or whatever. An indirect flash or lighting would work well, but haven't tried that yet.
. Mine seem to prefer face to face 
, but I'm getting ahead of my story! So here's the update: Last night before going to bed, I noticed that the eggs of the more red female were gone! She was the one due, so apparently the eggs hatched, however, try as I might, I just don't see shrimplets. 
Her egg count was low, so in a 20 gallon tank, it's going to be almost impossible to spot any shrimplets. The other female's eggs should hatch in 3 - 4 more days.
. But if you squint, hope you can see them lying on the gravel together.
this lasted longer and think it was a take; about an hour later, her eggs had dropped down into the pleopod area - so she starts this process all over again!
Your shrimp seem rather eh,umm...happy.
Solaris, this is all in the name of scientific reseach, right?
