I have bought two of small CO2 Atomizers 2 weeks ago... The brand is UP-Aqua from Taiwan. I setup DIY CO2 and 2 days later bubbles started coming out. I do have few glass diffusers and I like this one better since I use DIY CO2 and bubbles seems to be smaller.
My blue bees in my tank for 3 weeks now. So far, none of them have died... These shrimps very active and lots of female like to hide in dark places. The funny thing about blue bee is that they don't stay with same color everyday. These shrimps do change color everyday between brown, blue or purplish colors. The color of the shrimps that shown in pictures are kind of purple to brown and more thicker color then before. I sometimes do see blues colors as well. What I noticed is that, these shrimps are just little smaller than CRS... 
I had about 40-50 of these shrimps and dude to work and my real life, they all died expect 13 shrimps... The tank has bee reset up and running about 1 month now... So far, they are eating well and moving healty. Also, I found 4 berried brown shrimp this morning!!!
I got my shipping today. These are 12 blue bee shrimps (paracaridina sp.). What I read was color of these shrimps are dark brown to light brown and blue color. I did about 50mins - 1hour, acclimating these shrimps before putting into my tank.
Seller gave me 3 berried shrimps and one with half berried shrimp! Last picture is taken 1hour later introducing them to my tank. So far, I see none of them with blue color... but, I'm hoping I get some blue with in few days. Right now, they are gazing ground and looks like they are doing good.
This tank hasn't been cleaned for over 1 year? and I felt like cleaning today. I took out all the substrate and plants out. Now, I needed to clean the glass and I accidently hit the corner of table while I was moving the tank. I heard some noise and I found side of my glass is little cracked!!! There goes my 20 gal tank... -_-
