Shrimp acting weird

I have 6 shrimp added to a cycled heavily planted 5 gallon tank.

After 3 days, one shrimp started acting strange. It would swim in circles around the tank, then the next morning I saw him swimming himself in a loop, turning himself upside down.

As the day went on, he moved less and would lay on his side, still moving periodically but not very much.

I’ve moved him into a smaller cup of tank water in case he passes away/to be able to keep a better eye on him. He still occasionally moves but less.

No one else from the tank is acting strange and I’ve noticed a bit of molted exoskeletons on the ground (3 visible).

The tank is 0amm/0nitrite/10nitrate 4kh/8gh & right before I noticed this, I did add less than a gallon of water to replace some water that had evaporated.

Does anyone know what this is or what is happening? I’m very new to shrimp. The shrimp also has the little white line across his midsection.

How did you acclimate them? I assume these are neos. If the water parameters from LFS/breeder is far off from yours, that could cause failed moltings and even death, even if you have "ideal" parameters. This is usually only a problem within the first day of acclimating them though, even the first few hours where osmotic changes have occured quickly. The white crack is usually indicative of a failed molt. Your parameters seem pretty good to me but again, if they were previously thriving in a GH of 12, then that could be an issue. Also, what is your water temperature? Shrimps generally prefer cooler waters.

As for the shrimp that's acting weird, it could be bacterial or parasitic, so quarantining that one was a good idea. Sometimes adult shrimp have a hard time acclimating to a new tank and they just die for no apparent reason. It's common to lose one or two shrimp at first. If you can get through the first few weeks with them, they'll usually do just fine. Once they start to breed, the next generation is usually quite a bit hardier and your colony will grow.

I did a drip acclimate but only for an hour (had to run for work), so maybe it was too short 😞

Yes, sorry they are neos. They are bloody mary’s from FlipAquatics; they are suggested to be kept at a GH between 7-15. They were imported by FA and they say they quarantine for 30 days before allowing them to be bought. I have very soft water and raise it with Salty Shrimp GH+. Maybe it is because they use RO water and I don’t that gave the shrimp a shock 😞

My temp is kept at 72, I use a heater to make sure it’s consistant. Is this considered high for shrimp?

Thank you so much for your answer, I’m really sad to lose one even though I knew it was somewhat typical.

All the other shrimp seem very healthy, I keep a close eye on them. I hope this is my only loss!

72 degrees is just about perfect. You should be fine there. I've bought shrimp from Rob over at Flips. His shrimp are about as healthy as you'll find anywhere else. I know he has home bred Neos for sale too, not all of them are imported. These will have a higher survival rate and are best to purchase, if available. I know that most, if not all, of his caridinas are imported. I did end up losing a black panda shrimp from the batch I purchased from him. It's growth was stunted for some reason and never grew to adult size. It died after a month. I don't think it was much over 1/2" when I scooped it out of the tank. My parameters were pretty spot on with tons of biofilm available. The rest of them were fine and I even noticed some berried females soon after. Sometimes these things just happen at no fault of our own. Hopefully you'll have better luck with the rest of them.

Thank you for all your advice 🙂 I feel much better about the whole thing, especially since you’ve bought from FA too!

I wish the homebred option was there for BM shrimp but it wasn’t available so I took the risk. Their color is amazing though, and he did give me an extra with my order so it’s not too bad! So weird you had one with stunted growth. I hope the rest did well 🙂
