New Shrimp Death

[jossswonk]

Two days ago I got my cherry shrimp in the mail and they all appeared to be doing well until I came back from work today and found 4 dead. I had just done a water change on the tank before I put them in so there shouldn't have been any water quality issues. Other than the new shrimp, the occupants consist of a healthy population of snails. Do you think it's just the new environment that killed them? I noticed that at least 2 of the dead shrimp had a white ring aroun where the carapace connects to the rest of the body. Any advice would be welcome.

I don't add shrimp into new setups.

This is a pretty well established tank. It has live plants and has been set up for a while

^ I misunderstood.

With my 60L, I added 25 shrimp to my tank and found within the first week or two 6-8 died, mainly WROD. I think changes in water and the environment can impact the moulting, resulting in deaths. Now they breed and I have new shrimp every couple of weeks.

Should I be worried about the rest of the shrimp then? And it might be important that the tank has some algae growth but it's not crazy out of control.

I personally wouldn't be. To me it's bound to happen, survival of the fittest and such. Not every shrimp is hardy. The numbers should bounce back in a balanced aquarium. A little algae never hurt anyone . I watched a video by a shrimp breeder who said that he only ever scrapes the algae/biofilm off the front glass so the shrimp have the other 3 to graze off. The more biofilm the better.

As far as I know, most pest snail excluded, moving invertebrates from "unknown" water source can be a very painful experiences. And dripping solidly new additions is a must.

No matter how good they look when you get them. They Molted couple times, sellers knows that the biggest thick looking shrimps are going to sell like donuts at a good price and will molt less often as they are aging and thereby reproduce less (see reproduction)... But they are the ones that have the lest chances of survival. You need to get at least a berried one at this point.

But juveniles are pure breeding stock ready to happen. The cycle is rapid and smaller shrimps go by changes like nothing.

It's difficult to convince someone to buy shripadoodle so small they think your messing with them. But when they see them exploding in their new tank.

Is a pretty good sales point for me.

While looking in the tank I see at least one really small shrimplet so there is hope!
