Urgent Fire shrimp dying??

I have a fire shrimp in my tank and it is upside down moving it's legs in a weird way. It molts about once a month but I've never actually seen it molt, just saw the shell. He is out of the cove he is usually in, but I never find the shell in his cove so it might not be a big deal. Is he molting? Or is it dying?

My water parameters are stable, corals and fish are doing fine. Did a water change earlier this morning and added a clove coral last night along with a small serpent star.

 

I'm pretty sure he's dying.. Snails are coming after him.. He isn't moving as much.

 

I opened up my cabinets and found my skimmer overflowing!! I forgot that I added the aquastick epoxy to move a zoa! Could it have been the toxins from the stressed zoa??

 

Someone help the guy!!

 

And its dead...

Now id like to find out why.. Can palytoxins affect fish/inverts?

 

In my experience shrimp are the most sensitive to any slight change in the water be it salinity or parameters etc. I stay away from epoxy cause 9 tines out if 10 it makes my skimmer go nuts. Could be the chemicals fron it. Any other recent changes?

 

Sadly, there's not always an answer or solution to every problem where the life or health of livestock is concerned.

Considering that the one shrimp was the only thing affected in the entire tank, my first guess would be that it possibly stressed to death over a failed molt. Totally unrelated, and simply put, purely coincidental concerning the timing with the other situations.

 

Just the addition of a serpent star and clove polyps. I don't see a way around the epoxy because superglue alone doesnt work very well for me. I usually do a pwc after its cured though. I dont think that's what caused it.

 

I completely understand, If there isnt an answer, there just isn't. Wouldn't a failed molt be a sign of a lack of iodine? I thought that was something that helped molting. I know it isn't calcium, my sps are great. I guess it could be a coincidence but It happened so fast after I moved the zoa, it seemed to weird. If palytoxin is a neurotoxin, wouldn't that account for all the rapid leg movement along from the nervous system being affected?

 

First, I am sorry for your loss...

Iodine may help in molting, but it does not guarantee that every crustacean will molt successfully every time. Sometimes, a molt just goes awry, pretty much like anything else in life.

The palytoxin should have affected the corals and possibly other inverts if that was the problem. I'm not positive, but I doubt it's a neurotoxin, as it is designed to attack other corals, which do not have nervous systems. Also, twitching legs, etc can be caused by the stress, panic, or just plain muscle twitches from a dying creature during it's last moments, regardless of the cause.

Honestly, we'll probably never find the cause of death for every creature we lose. A failed molt is only one possibility with your shrimp. All animals on earth face a world of diseases and parasites that, especially with aquatic life, are impossible to detect and cure. We can only see the one's that affect them on the outside before it's too late.
