Having a couple DOA is common if you ship in poly bags, and seems almost unavoidable.

If you ship in breather bags, a few DOA indicates that something is wrong.

I highly recommend drip acclimation.

Thanks for the helpful comments. They were in polybags and I don't think I gave them long enough to acclimate to my water before completely releasing them.

Thats usually the biggest cause of deaths upon introduction to a new tank. The acclimation period is the most important part and is more time consuming than that of fish usually.

I simply haven't set up a drip acclimation yet, but since most of my tanks are controlled by house temperature I just empty the bag into a large plastic bowl on the counter. I add about 10cc every hour to that bowl from the tank they are going in. I usually end up with double the volume of water in the bowl, then I slowly dump the bowl in the tank after the temps match. Never had any deaths from acclimation.

In the last month I've placed two small orders of shrimp. Both were shipped priority mail and arrived within 2 days. Both packages I had held at my post office and picked them up there within a few hours of them arriving in order to spare them a bumpy all-day ride on the mail truck.

However, both shipments (from different breeders) had shrimp that died within a few hours of introducing them to my tank. It would seem to me this may be due to stress of shipping and I was wondering if these losses are normal or what I can do to better acclimate the shrimp to their new home?


My first order was 5 CRS. Within hours of placing them in the tank, three of them shrimp were already dead. This was weeks ago and the other two remaining have thrived and gotten much bigger.

My next order I got today was for 8 cherry shrimp. Again, within hours two of them are dead. The rest appear okay for now, but I wouldn't be surprised if another couple died within the next 24 hours. Has anyone else experienced this? Is it shipping stress or my tank? If it's my tank, it must be healthy enough to support long term life, but perhaps the parameters are shocking? I'm leaning toward it being the result of shipping stress, which is why I want to know if it's typically to lose a few shrimp shortly after getting them.

Looking forward to the responses.
I think you are not examining the situation for what the evidence suggests. If shrimp survive two days of transit, sitting for a couple hours at the post office, and then subsequently die after a couple hours in your tank, it seems the evidence is pointing towards actions on your part. Ask yourself if those shrimp would have still been alive for two hours longer in the bag verses two hours in the new tank.

It seems to me that something is occurring during your acclimation phase or something in your tank is problematic for the shrimp. I only mention this because that is the way I see the information pointing to and wouldn't want you to continue purchasing shrimp with the expectation that they should die.

I just see it differently. That they were going to die anyway from the stress of shipping and they just happened to pass away in the tank. The fact that they die within a couple hours after being added, while others survive for weeks would suggest that there couldn't possibly be something lethal enough in my tank to do in a shrimp in a matter of mere hours or else- how could the others even be surviving at all?

I'm not completely ruling out the possibility that it's my tank though- it just makes a little less sense to me. I suppose one method of testing would be to purchase local shrimp and bring them directly home, thereby minimizing stress and see if any pass. Of course I have tested my water and it's within range for cherry shrimp.

Not true. Not all shrimp are created equal. Some will tolerate shifting parameters better than others. Survival of the fittest one might say. Just because they didn't all die doesn't mean you acclimated them properly.

Hmmm, I don't know. I certainly don't want to rule out the possibility that it's my tank's fault, but I am just surprised the water could be lethal to one shrimp so quickly and not kill the others. Maybe over time, yes, but something must be seriously wrong if it's the tank alone- can one shrimp really handle what very rapidly kills another?

FWIW I drip acclimated my PFR's for 2+ hours before putting them in their new home. I've never noticed a dead shrimp since.

No mystery there. It has the same relevance of two people getting shot. One dies the other lives. Mental and physical stress can all be handled differently.

* Satire *

Stress from being in a little dark box. All of a sudden a few days later there is a lot of light, being swayed around in a little clear bag of your own feces and slowly dying from asphyxiation, and some creature keeps screwing around with you in a fruitless attempt at counting all your buddies as he almost puts you into anaphylactic shock by changing your environment.

With adult shrimp, you do have to do longer and slower drips.
I don't think shrimp that have been in a shipping bag for a couple of days are in water that is relatively the same as the source. I think the water in the shipping bag contains less oxygen and more ammonia than it did at the source tank. Even if they were going back to the source tank - let's say seller shipped to him/herself - they'd need to be acclimated.

Well usually if this was from one breeder I would say 50/50.
But, it seems like since its from two breeders it would point towards either....

A) There's an issue with acclimation
B) There's something wrong with the water
C) Your water is too drastically different from the breeder's water

Rarely....
D) The middle man, something about the post office is screwin with them.

I have found that drip acclimation to be the most effective and the primary cause for death after day 1-10 of introduction is acclimation process. But yeah if they're shipped in poly bags, do drop prime in there immediately.

One has to realize because shrimp don't have "skin" and they are invertebrates, they are much more sensitive to changes in water quality since they don't have much regulation of mineral and water exchange with their body.

Best way is to buy from reputable peeps with kordon breeders. TBH I think its no doubt and undisputed best bag to ship shrimp in so........you probably shouldn't buy from those guys again lol......good sellers use kordon breeders when possible.
