Sudden shrimp deaths

Woke up this morning to five dead Amanos and five others on the verge of death (pale, upside down, but still alive). Three others appear to be fine. Ammonia is 0 but nitrates are around 60 or so. I am EI dosing, so this doesn't seem to far out of line. Coincidentally, I bought some new plants that arrived yesterday and plopped them in yesterday. I noticed the shrimp zooming around as soon as I added them, but didn't think anything of it. Are there certain plants that are poisonous to Amanos?

Your nitrates should be below 40 that may be one issue. Maybe there was some copper in the tank you got the plants from? I always soak mine at least overnight. Some kind of quarantine is always a good idea. I dodged some planeria one time doing this. ;)

Some plant nurseries will use chemicals to kill off snails/eggs, these treatments can certainly kill shrimp too so it could be due to that. Always rinse new plants and pick through them thoroughly. Quarantining them is a good idea but I’m too lazy for that and just soak them in a bucket overnight after rinsing and prepping them.

I haven't changed anything else so I'm thinking it has to be the new plants. Any chance the sick ones will recover?

I just tested for copper and there is none. I'll contact the nursery and see what they have to say.

I just heard back from the nursery. They said they absolutely do not use pesticides and they have shrimp in their water. No clue what happened then.
