I keep my RCS with plecos.
I would think Endlers or some of the small rasboras would probably be your best bet. Even they would likely get some shrimplets. You might want to have one "safe tank" as you breeding tank and then thin the adults out into a tank where there shrimplets might get eaten. If you leave your best adults in the breeding tank, you should increase the quality of your strain.
