Shrimp disappearing

Betta-Chetta · Jun 20, 2015

OK guys so I am curious to see what y'all think. So three months ago had four cleaner shrimp and one tiger pistol shrimp. One night every one was there and the next morning all of my cleaner shrimp disappeared. A month goes by and I buy two more cleaner shrimp. And about a week ago those two disappear. The day before they went missing I had added a peppermint shrimp. Then about two days ago he has disappeared. So what would be causing them to just disappear. They were all very health and eating fine. I know with high nitrates it could kill them but I only have about 5 nitrates. All my shrimp are gone and all that is left is my pistol shrimp. I highly doubt that he would kill them since he is always under the rock and only time he comes out is when I feed. The fish I have is a mocha clown, four stripe damsel and a six line wrasse in my 75 gallon reef which is where my shrimp are disappearing. So if anyone has any ideas let me know. Thanks guys!!!

could be a pest in the rock, could be a fish in your tank that isn't 100% reef safe

Any chance you have whelks, fish who aren't invert safe, or gorilla crabs?

Oscaror- no all the fish are reef safe cause it is only those three that are in there but they would eat them if they just died.
Haleyf1024- no maam nothing like those are in the tank :/. It is just very puzzling for what is going on with it.

I have a mystery wrasse who ate my two cleaner shrimp. I don't know if he killed the first one, but I caught him attacking the second one. The six line is closely related to the mystery wrasse and might be the culprit.
