That is low. If your tank is 70TDS, it means your source water is even lower.
It's uncomfortably low for Neocaridina. Can you get your hands on GH+KH remineralisers? Something like Salty Shrimp GH/KH+.
It doesn't have to be the Salty Shrimp brand. Add it to your change water to bring TDS up to 100 initially.
Ammonia seems to be at 0ppm or 0.5ppm. Nirites is at 5ppm I think. Sorry I measured all before leaving the house but left my notes at home. I found KH and GH at 0ppm which is very low and TDS at 70. The water I've been using is very soft.
You can usually see through blue jelly shrimp shells so there is a difference between being able to see through the light colour of the shell or seeing through a shell which is clear colourless or even a hole in the shell!
The black on the blues may be part carbon rili colouring, if it is on the shell? From what I can make out from the photos I think it is on the shell and may just be low grade colouring?
Thank you guys. So exciting to see a jade green shrimp haha. So crazy it came from 2 blue Neos.
Again, tank seems to be back to "normal". I spent a few days without feeding them since there's algae around...but yesterday I dropped half a wafer and they all came like crazy. I took a few more pictures to show you the clear area on the head.
