Are Shrimps A Good Idea For My Aquarium?

I have a large planted aquarium(40g) with parkinson and dwarf neon rainbowfish, redline torpedo barbs, pearl and honey gouramis, yoyo loaches and a bristlenose pleco. Ive always been fascinated by aquarium shrimp eg bamboo, ghost and red cherry. But are my fish too big? Dont want to add some and they become an easy meal for my fish. Also how many would you suggest getting?
