I’m so frustrated and would really love some help. I have a 5l jarrarium which I have had going now for 2.5 months. Fluval plant and shrimp stratum topped with crushed quartz sand with crushed coral pieces, drift wood, moss balls and plants. I have gotten cherry shrimp twice now and the same thing happens.
Acclimate for around 3 hours, start to go lethargic and then when added they seem great. Eating, swimming round…then about an hour later they start to go slow, maybe go on their side or randomly go completely still and jerk round. Now they are all on their side with just their legs twitching at most. I just don’t know what I’m doing wrong! Parameters below, please any help would be much appreciated!
Copper – 0ppm
Nitrate – 0ppm
Nitrite – 0ppm
Free chlorine – 0ppm
Hardness – 125ppm
Total alkalinity- 100ppm
Carbonate – 100ppm
pH – 7.2
Temp- 17c no heater
No filter but run and air stone for a few hours a week to ensure enough oxygen from plants. Light on for around 6-10hrs per day.

17c….. if they’re neocaridina you are freezing them caridina do a lot better in colder water, my parameters in my shrimp jars are roughly the same accept just a bit low ppm on carbon and hardness in at 80ppm and they’re reproducing in my jars (multiple) so I honestly think it’s just the temp, maybe stop putting air stones and allow the plants to fill that niche as well
Edit: reread it says hardness is 0ppm shrimp need atleast 80+ppm hardness to malt successfully, sounds like they go in stressed and then try to malt due to the stress and can’t actually complete the malt leading to death
First, recommend posting this in /shrimptank. Is not a problem with your jar.
Neos can survive down to close to freezing. I keep them at 65° f in my house which calculates to 18°c . They certainly don’t die in three hours at that temp.
My guess is pesticides, perhaps something that acts as a neurotoxin.
