Keeping different shrimp in same tank

[spit.fire]

I put I peppermint in my tank about a year ago, never once seen him until about a week ago but mine never touched aiptasia as far as I could tell.

From my experience the only shrimp that you don't want to mix is coral banded shrimp as they can be hit or miss towards other shrimp

Mine killed a harlequin, and it's mate (they were together for about 4 months)

Although I have had a coral banded with a skunk cleaner but they were in an 8' long tank and probably never seen each other as they stuck to opposite sides of the tank
