peppermint shrimp died but parameters perfect?? Help

[Valkie]

I recently cycled a 10 gallon nano reef and got some inverts- 1 zebra turbo, 1 dwarf hermit crab, 1 peppermint shrimp, 1 pulsing xenia frag, and 1 zoanthid frag. Everything seems perfect. Temperature is 78, salinity is 35, Nitrate is 5ppt, Ammonia 0, Nitrite 0, pH 8. I drip acclimated all animals before adding them to my tank. Everything seemed fine last night and I woke up to a dead peppermint shrimp. The turbo is alive and moving, the xenia seems stressed but alive- polyps open and pulsing, and the zoa is still stressed out but 1 polyp is starting to open.

Are any of my parameters even slightly off? What other reasons could there be for the peppermint shrimp dying??

Sorry to hear your loss. :( There's a host of possible causes beyond the basic levels you've tested. But are you sure it's dead and didn't just molt? (I've known a lot of shrimp get named "Lazarus" because their molts were mistaken for bodies. ;) ) I would want to know what calcium and alkalinity are in addition to what you listed. It could be it was already stressed from an already existing issue or from previous handling and the stress of moving it again overwhelmed it.

Peppermint like a little cooler water also.

How long between addition and death?

Where did it come from?

This is one aspect of the hobby not talked about much. Things just die for no reason on occasion. We've all had it happen. While Im sure there is a cause most of the time we never know.

We had two cleaner shrimp since almost the beginning... 2 years thereabouts.

First one molted near a power head and unfortunately fed the tank. That was quite a while ago.

2nd one just recently disappeared. no reason.

Are you sure it just didn't molt? I thought mine died and it had molted.

The other thing is if your parameters are spot on, it could have just died. Maybe it was stress? Maybe it was disease or something else?

With inverts it's not always easy to know how old they are. Maybe it was just near end of life when you got it. Not highly likely, but hard to rule out unless it was clearly a juvenile.
