Shrimp zombie


Something really weird just happened and I need to share this with someone who understands shrimp or I may explode.

Last night one of my crystal shrimp fell over dead for no apparent reason. I noticed it when it had just started dying -- it was on its side, with its legs all outstretched and twitching a little. Nobody was harassing it yet so I thought the least I could do for it was to let it die peacefully without anyone eating its face. I transferred it to a tiny plastic cup and let it float at the surface while I tested the water. There was nothing amiss with the tank... all parameters were normal and stable, I haven't changed or added anything recently, and everyone else in the tank looked healthy and busy. I couldn't find anything wrong with the tank but I did a small water change for good luck and left home to do some errands.

After a few hours I came back home and the shrimp was lying on its side in the cup with its legs all curled up like a bug, looking extra dead. Normally I would have thrown the shrimp away but I was in a hurry to get dinner started so I left it there.

After dinner I took a look at it and it was sitting up, looking normal. What. I changed the water in the cup and the swirling water knocked it off its feet but it righted itself every time. I also saw it grooming itself and swimming weakly.

I left it over night. I expected it to be dead again this morning but sure enough it was looking fine! I changed the water in the cup and it flipped out and LEAPT out of the cup and into the tank. Since then I've seen it preening and foraging like normal. You'd never know that less than 24 hours ago it was dead in a cup.

WHAT THE HECK

Did my shrimp just have a seizure or something? What did I witness?!?!

I named it Lazarus. It ran off into the tank somewhere and I don't know where it is. I hope it doesn't bite any of the other shrimp.

Good question. I've experienced some similar activity with my PFR's and its really bugging me. Same story. Nothing has changed except the shrimp acting very strangely with the same activity that you are seeing.

Just out of curiosity, are you using any ferts or excel?

I have been using a little Flourish and Excel in very small doses (1/2 dose every other day) for a few months without problems. A week ago I stopped both. I feel like if anything were going to happen it should have happened earlier, when I was actively dosing, but what do I know?

I have had this happen in a tank I saved most shrimp. I think it got a ammonia spike from the soil that kind of gasses the. And they losses function. That is my thought as that is what it seemed in mine, then I moved mine to another tank and they all slowly came back

I don't use any ferts of any kind in my shrimp tank. All I have right now is a small layer of sand and floaters.

Low oxygen does that. How much surface agitation do you have?

Thank you mordalphus, I think thats the problem. I have a sponge filter with a heavy cover of frogbit that may be impeding O2 exchange.

I don't know if O2 is a problem in my case... My canister filter's spraybar agitates the surface a lot. I also have a 10" long airstone (this is a 10-gallon tank) that I let run all night. During the day the undersides of all my plants are covered in bubbles.

Well, just in case, I'll let my airstone run all day today too.

Ahh, but could be not from a lack of oxygen in the water, but a lack of oxygen in the shrimps blood... Aka it could be co2, ammonia, etc which damage gills.

I wouldn't worry a whole lot unless it starts happening to other shrimp. It could have damaged it's gills during its last molt or something. But it might be a little more 'special' after all of this lack of oxygen

I have seen that happened to shrimp that had just molted. If a shrimp does not have enough energy reserve, it will be very tough to go through the starvation required for molting. Right after getting out from a molt, such a shrimp may not have even the strength to stand up. But if it is allowed to rest for an extended period of time, it will eventually recover.

Anyway, I can say that I've not witnessed this in any of my shrimp tanks, however I will say that I have some type of air pump driven thing in each tank whether its a bubble strip, air stones, sponge filters etc...
