I do not have much experience with shrimp, but am curious what you guys do with substrate vacs and these guys.... do you just vac normally and find they move out of the way? Even with a grate on the python I'd fear sucking them into the flow.
all those shrimp I listed will interbreed resulting in offspring that would probably look similar to the wild type neocaridina. You can take a look at my compatibility chart which should help you identify species that can be housed together without crossing.
