I have 3 tanks of about 30L each.
The oldest has ember tetra, neon tetra and red cherry shrimps in it. The majority of the cherry shrimps have gone wild colour now as I didn't cull. It is fairly densely planted and just uses dechlorinated tap water!
I then have a betta tank with a male betta where I sometimes dump some of the cherry wild shrimp in either as food or company for the betta. That tank has also become densely planted. I use tapwater for this tank but add GH and/or KH to get to near the parameters JayC here recommended and that seems to work perfectly. I tried with just tap water (dechlorinated) a few times before but it never worked but thanks to JayC advice it now runs fine.
Now for the last tank. This started out as a Taiwan Bee tank and went unbelievably well using zerowater and shrimp minerals. You can see photos on this link, scroll down to 30 Dec 2018,

Following the heater stiicking on in that tank and cooking all the stunning shrimp I couldn't get it work when I re-did the tank, I have had to assume the substrate has something to do with it (???) as it has never grown plants well etc and the tank looks very drab/brown, not the lush green of the other tanks or the same as it was in this tank with the other substrat? I will use the substrate I used before if/when I have another bash at TB shrimps sometime in the future. At the moment I have a killie and 11 mosquito rasbora in that tank!
Would love to hear all about your setup(s) and experiences as I am definitely a HUGE Taiwan bee shrimp fan, and still disappointed with what happened to mine................
