Did stress kill my shrimp?


I had 4 cherry shrimp in a 2 gallon bowl. Everything was good for about 5 days, the shrimp were molting and it was great, I was keeping up with my every other day 40% water changes. I decided to grab some more plants, after planting about 15 groups of micro sword in a tight area I think I stressed the shrimp way too much cause they don't have a lot of space to hide while Im planting. The next morning I wake up and 3 of them have died Do you guys think the stress killed them? If so how should I go about planting additional plants in the future? I dont want to stress the little guys

Did the shrimp just molt? I would wait until they stop molting as they are delicate in that stage.

How long was the bowl set up? What are the water parameters? Why are you doing 40% water changes every other day?

It's probably the 40 percent water changes that killed them.

No need to change water that often or that much for a shrimp tank.

Where did you get the hair grass? Was it one of those packages? If so, sometimes they are treated with copper to make them snail free. A couple people have found out the hard way about those plants.

Hi everyone, I'm new here.
Another possibility, what happened in my shrimp tank, is at night the plants gobbled up all of the oxygen. Some survived by gasping at the top on the floating baby tears. I added a mini bubble strip and the survivors immediately got better. I now run the bubbler at night after the lights are out and everyone has been happy and okay. I'm surprised the shrimp like playing in the bubbles, I always see advice that says they like the water perfectly still. I guess they like breathing even more than that.

*Edit, it was probably just the water changes and possibly stirring up the substrate planting the new plants in.

Plants produce oxygen not "gobble it up"

When it's lights out or really low light, plants do use up oxygen, although not sure if it's enough to deplete the water column of oxygen.

On this note, Melissa71, you probably had bad surface agitation that didn't allow enough gas exchange.

Well the parameters were:

Ammonia - 0.25 ppm
Nitrite - 0.00 ppm
Nitrate 5.0 ppm

Should i not change that much % of the water? Or should I change it less often?
I just thought it was odd that they were all fine and as soon as I disrupted the water and substrate they all died immediately. Eco-complete substrate and a 6500k bulb if that helps

I was also thinking of making some sort of circulation pump to get a little flow. Thoughts? Also any ideas how to make one?

Your tank does not appear to be cycled.

Hmm..

1) Have you cycled your tank? How long has this tank been running?

2) If it is cycled, then good job! You don't have to chance 40% of the water every other day though. That is very dramatic and unnecessary. 15-25% a week is fine.

3) If your tank was cycled, then it was probably planting the micro swords that did it. Disturbing the substrate too much can cause ammonia spikes which end up killing livestock.

Its been up and running for a little more than 2 weeks, how long should a tank with no filter take to cycle? Also how does a tank with no filter cycle?
