I'm trying to keep shrimp/ crayfish in my paludarium. They look healthy when I add them, but die overnight. I just got a crayfish yesterday as I thought the problem was over as I got rid of flatworms in the tank. The crayfish was doing okay yesterday and this morning, but within 30 minutes went from active and healthy to not moving and curled up. What could be the cause and is there any hope for my crayfish?

Water is medium soft
~6.5 ph
Almost no nitrate
No nitrite or ammonia
Has 2 airstones, a filter and powehead
Many hiding spots
3 flagfish
Some mosquito fish
Pond snails
Newt
Everything that's not a crustacean is thriving
Tank photos
I have a video, but I'm having problems uploading it

The newt was from a different tank. I want to try shrimp again, but they die too. The newt is almost always on land anyways. I would love to keep cherry shrimp, but I'm looking for any easy to breed crustacean

I thought that they were easy to keep (though apparently not in this tank), but everyone I talk to in person says they are hard to keep....so


I don't know what's going on in there

What could be the problem with the tank? I thought I had flatworms in the tank and used prazi pro, but the deaths are still there. 99% of the time they die overnight, but this crayfish started during the day.
Here is when I tried the shrimp

1st thing in the tank
A second test as 1st batch was potentially "bad"
After a couple of small water changes and 2 weeks before fish
1 time after mosquito fish
1 time after the flagfish
This crayfish I tried a couple days after prazi, plants being added,airstone added, etc

What is your kh? Have you tested your ph first thing in the morning/afternoon/evening?
That is the only thing I can think of that would kill overnight. And maybe the stress from the ph swing killed the one that died during the day?
