Murderous Cleaner Shrimp

[doch]

I used to have 4 cleaner shrimp (all hung out together) and 2 fire shrimp in my 160 display. All seemed well and good between them all. No fighting, or deaths. Unfortunately, I lost all of them when my chemistry went all wacko and crashed my tank. I just bought 2 cleaners, planning on buying a couple more... maybe I'll pick up 2 fire shrimp instead.
