Basically any fish that can fit them in their mouths will treat them as lunch. Some are more likely to do so than others. My weather loaches for example don't seem to have noticed that they're potentially food, but I wouldn't mix them with all but the smallest cichlids. Even fish not big enough to swallow them can pick at their legs and pester them to death.
How large is the tank you currently have, and what stock have you got?
ETA: Looking at the stock you have on your profile you'll probably be OK, but I'd be a little concerned about the rainbows. I've not kept them myself so I can't say if they're shrimp-safe.
I have cherry shrimp and amano shrimp with my betta, although he does stalk them occasionally, they seem to easily jump out of the way if he gets too near. There are plenty of places for them to hide and the cherry shrimp seem to be mainly nocturnal anyway.
