Excited to have a new project (as if I ever really get "done" with the others

Anyway, I would like to do a shrimp tank and was also going to add some other small fish.
trying to decide if a few Ender livebearers would be better than a betta pain.
any thoughts?
I am also wanting to maybe add a couple of kuhlis if they would not be too much!
will they eat the shrimp?
3 shrimp, 2 betta and 2 kuhli does not seem like too many fish as they all stay small, but I may be underestimating bioload.
also, my plan is for it to be a planted tank, fluorite substrate and naturla driftwood for hiding out.
what do you all think?
does anybody have any better ideas (since I am not the most creative person around!)
