This subject has come up daily lately! Long and sort of it is, it's fine. Neocaridina shrimp (cherries and their color variants) are FAR more adaptable than bees; and if you're going to keep both, best to cater to the more sensitive shrimp. pH swings from 0 dKH certainly are nothing to worry about with buffering soil keeping things steadily acidic. I breed Neos in Caridina tanks currently. I can't say scientifically that they have the same survival rate of offspring and such, but they seem to be normal, thriving colonies. When I tried keeping bees in Neocaridina conditions, that didn't work out so well.
Nothing good happens fast in an ecosystem.
