Thank you all for the responses!
I'd say they're probably hiding. New shrimplets are only a couple millimeters long and have very little color, so they aren't all that easy to see. They're probably in your jungle feasting on all the biofilm so they wouldn't have any reason to come out anyway.
Spot on! I saw one, it looked like a tiny blue eyelash! He was dwarfed by those little shrimp wafers, but trying to scarf one down anyway. Fingers crossed he makes it and there are more!
You should buy a GH/KH kit and see what is happening with your water. Here in San Francisco the tap water is decent for shrimp, but it changes a lot. One month it's KH 0 GH 2, next month KH 3 GH 5.... All of this will mess with your shrimp's ability to molt and give birth, if not survival alone.
I do have an API Master Kit and supplemental KH/GH Kit.
More on that in a minute- Our water here is liquid rock, but at least it's stable. It must be a real challenge when your source water is all over the map.
"Local tap water" might not mean much, since some homes may have water softeners installed in them and the piping can be different.
If possible, I would recommend finding out what the tap water is where the shrimp came from, as well as the parameters of the tank they are living in. Those can be two completely different things.
As mentioned though, you might have shrimplets and they could be hiding. I'm curious though if you have any pictures of when the female was berried???
Also recommend getting a liquid GH and KH test kit, either by API or Sera.
I've been going to this particular LFS for about 12 years and spent hours chatting with the owner and staff. I do know they don't treat the water other than removing chlorine-They may age it, there are always open tanks of water under the racks aerating. They house stock in individual tanks with their own filters. We are all on the same water in Las Vegas other than, as you say, piping. I know they are on the second generation of Blue Dreams in the store tank- they breed like cherries
The breeder is a long time customer of theirs and lives here. They assure me he doesn't do R/O or softeners. There are occasionally caridina in the LFS, but their tanks are marked R/O in big letters. I do understand that there will be variables despite the fact we are all on the Southern Nevada Water Authority feed. No good photo of her, I'm adding one of the tank, but my camera phone is pretty bad. (It's not cloudy, I'm reflected on the front)
+1. You are screwed without a GH/KH kit.
I'm screwed with
Tap water here is tends to be ~ KH 190, ~GH 360, pH 8.2. Perfect Rift Lake water, no adjustment needed, lol. That's close to what I test. As was pointed out, there will be variances. My liquid G/H K/H test of the shrimp tank gave me a KH 8 drops, GH at least 25 drops (lost count around then when I saw the shrimplet, but a lot
). pH 7.6 The API test strip gave GH 250 in my tank.
I've been topping off with R/O to prevent more concentration of "rock" due to evaporation. I change maybe a gallon a week and maybe a pint of that is R/O. My LFS said clean and stable was most important.
