Hi guys, I was thinking of getting some shrimp for my planted tank. I'm just afraid my fish might eat them all up cos the shrimps look so small and fragile! What I've got in my tank are:

1 Sailfin Pleco
1 Red Finned Shark (Ruby Shark)
4 Platies
1 Neon Tetra (I know, they're schooling fish. The rest died. Am getting more this weekend)

I'm planning on adding SAE and more tetras in the future. Any advice? What kind of shrimp should I get? I'm getting them mainly for the purpose of keeping my tank clean (also because they look so damn cute! Haha!)
