Okay, so I ordered 30 Cherry Shrimp for $35 (that included delivery charge) on Jan 10th. I have a 5 gallon, cycled tank, which was temporarily housed by my Neon Tetras. Last week I moved the Neons back into my main tank to make room for the shrimp, and I fed ammonia into the 5 gallon to keep the filter happy.

I thought that I would get notified of when the package was shipped (2-3 day US Priority Mail), but imagine my surprise tonight, as I had beef on the stove and cooking up spaghetti sauce, when the doorbell rang, and there was my package from Illinois! Oh boy. I wasn't ready. The tank had recently had ammonia added to it, so it still tested at 2 ppm. Okay...okay...um...what to do? I finished cooking dinner first for the family, and scarfed down my food.

I then opened the box, expecting to find a bag full of frozen shrimp (it is winter, after all) - the heat pack was stone cold, and the bag was very cold to the touch, but I could still see shrimp moving around in there. I floated the bag in the tank while at the same time completely draining the tank to replace the water and get rid of the ammonia. I put fresh water in (and correctly guessed a good temp with my fingers as it came out of the tap) - 76F. Alright - first hurdle crossed.

So I floated the bag and started to slowly add some tank water over the next 45 minutes. At the last minute I remembered that I had not yet covered my filter intake pipe! They would have all been sucked right up. A quick plea to my wife caused a nylon stocking to materialize, which I promptly cut and secured to the intake with a rubber band.

These shrimp are MUCH smaller than I expected. To me they look like babies - many are perhaps 1/3 of an inch from head to tail. Others are a bit larger at maybe 3/4 of an inch. But as far as I could tell, none of them were dead in the bag. I scooped them into the tank without too much trouble. I think the shipping company included a ball of java moss in the bag, which I also put in the tank.

So we'll see how they do tonight. What a lively bunch of critters. I had no idea they would be so active - very interesting to watch. Kind of like watching Zebras on steroids. I hope they will still be happy and active when I wake up in the morning. Will post a couple pics later.
 
Very cool story hope it all works out. Mine like to swimm up the front of the tank and drift back in the current from my powerhead and swim back up and do it again haha.
 
The filter really produces a strong current in that small tank - you think the shrimp will be okay with it? It looks like they are playing in the current to me...
 
They should be alright but covering the intake would be good. I think a filter sponge cut to size works better than the nylon ime. It seemed for me that the nylon restricted the flow and the canister filter had a harder time getting the water back up and into the tank.
 
Good suggestion - I noticed that the nylon was already gathering debris this morning. I'll nab a filter sponge soon.
 
The filter sponge should be rinsed out in a bucket of tank water when you notice a small change in flow, generally every water change since it will also collect debris but not like the nylon. The sponges make great pre-filters.
 
A quick googling led me to the Fluval Edge Prefilter sponge being a good fit for the tube on my Aquaclear 20 filter - so I may give that one a try. Thanks for the suggestion!
 
Ah - disaster in shrimp land. I'm not quite sure what did them in, but over the first 24 hours their activity slowed, and I started seeing corpses. By this morning (36 hours) I see no living shrimp, although some could be hiding still.

The tank water stats show a low level of ammonia (0.25), and the pH is 6.0. So perhaps the low pH and the low level of ammonia were the source of trouble for the young shrimp? Since I was caught off guard on their arrival, I had to do the full water change, and my tap water ammonia is 0.25 to 0.50 by default, so it was not an ideal introduction for them.
 
The pH shift could have been the cause. Did you give them any sort of acclimitisation? Or did you just net em out and drop them in? RCS are usually pretty hardy as long as they are adjusted to the params of your tank. Do you keep live plants and do you dose with any ferts? Most trace liquid ferts contain copper and if there is too much copper in the tank they won't survive. RCS can take small amounts before they keel over.
 
I had to do a large water change prior to putting them in (because I had just fed ammonia into the tank that morning), so the tap water pH was about 6.8. I floated their bag for 30 minutes, and then did:

+1/4 cup tank water into bag, waited 15 minutes
+1/4 cup, waited 15
+1/4 cup, waited 10
+1/4 cup, waited 10

Then put them in the tank. But my tap water then settled out to a pH of 6.0 by the next morning, which is the normal level. I did not put any plant fertilizer in the tank. HOWEVER, since you mentioned it, I did throw a bottom feeder tablet in there the first morning. Since the tank was so clean I wanted them to have some food breaking down in the water - but I just checked the ingredients on the tablets, and it lists "copper sulfate" - isn't that safe for shrimp since it is not elemental copper?? Or did that do them in?
 
Hmm interesting. I'm not too sure but it could be possible that they picked at it a little and it might have done them in. It's too tricky to tell.

It could have been the cold weather during shipping, the pH(unlikely), or the food wafer.
 
Hmmm...thanks for giving me the info. I will stabilize the tank for a month or so and then try again, with different food!
 
In a month or so my little shrimplets I'm raising now should be almost full grown. I'm in va so the shipping might not take as long if your interested? Not sure how many if got since they're too small to see them all. Would only want S&H.
 
That would be awesome - I'll send you a private message...
