Shrimp Compatibility

[fishboytoo]

I was wondering if larger ghost shrimp would eat amano shrimp. I had a few amano shrimp and some ghost shrimp together, now I only ever see the ghost shrimp. The fish didn't seem to ever bother the amanos when they were out, so I'm thinking it was the ghost shrimp. Should the two not be kept together?

Anybody else have this problem?
