I’m sorry to hear this, definitely sucks to have happen but know you’re not the only one. Of the first 4 I introduced into my tank, 1 died in the first week as well. Could be an issue with acclimating or a failed molt. If it is a molting issue, I would highly recommend getting a GH/KH kit to see where you’re at. Just curious but what type of water are you using in your tank? If tap did you use a dechlorinator?

Idk how to edit my post, but it seems like the other two are hiding and cleaning themselves a lot. Is this a sign they’re trying to molt?
Ended up using cover for my tank as many shrimps are trying to escape it 😢
