I have Red Cherry shrimp, but in a tank with Kuhli loaches, which will not eat live shrimp. I've kept RCS with Corydoras, too.This is not good.
Bettas and frogs will eat the shrimp.
Frogs may eat the Bettas. They will eat danios.
African frogs will try to swallow anything they even think they can stuff in their mouths. We learned it the hard way.
