Say it's not so!

[sumpfinfishe]

I came home after work today to discover a wave of casualties in my reef

Found a half eaten cleaner shrimp, and two what was left of them- hermit crabs, not to mention i haven't seen my peppermint shrimp for a few days now. And no none of the above are molts, I pulled out two partially eaten crabs and a cleaner that looked like it just got back from dessert storm!

Checked all water parameters and not one was even close to being out.

So I'm wondering if I have a crab issue or I hate to say the M word- antis

The only other thing is I have a very small pistol shrimp, would the pistol be that aggressive to a cleaner and a peppermint

Also no visible signs of damage to any of the fish.
