I currently have a Betta in my 10g tank with 5 RCS (Which is how many I ordered, and received). I also had a Gourami in there. No casualties.
I wouldn't recommend you trying either though.

WHAAAAAAAAAAAAAA? How is a giant carnivorous cichlid going to be "safe" with shrimp of any size? Additionally, I should note that this is a 10 gallon tank.
