Shrimp dying in front of me - advice needed


I have had my 10 red cherries for 6 days.

They were super happy and busy.

I just did the first water change and added 3 plants. I thought I would add plants while doing water change to cause less stress.

Within an hour one started to behave wierd, and dropped to the bottom of the tank. I was hoping it was going to molt.

Now more are on the bottom and dying.

I did a 5 litre water change, my tank is 30 litre. Treated the water as per instructions. Didnt use water from hot tap, brought temp up by leaving bucket in a bath. Temp was fine.

I rinsed the plants in the water I took for the water change, should I have rinsed these under the tap for ages?

I checked nitrate before and after water change, before they started dying, and these were fine. I have just checked PH and that is ok too.

So I took out the plants and just did another 5 litre water change, I also put the pump on full to move the water round.

I totally suspect the plants. Is there anything I can do, a larger water change?

3 are on their backs, the rest are pretty still and two are fine.

Any advice would be appreciated - I'm gutted right now

Give us actually numbers .. not "fine"
Ammonia?
Nitrates?
Nitrites?
Ph?
Tank temp?
How long has the tank been set up?
What brand water conditioner?
Test strips or liquid test?
Was there a chance any chemical or contaminant was on you hands?

Agreed because sometimes what is "fine" really isn't. However, your plants may have pesticides or some kind of ferts that's harming the shrimp.....in which case I would immediately go and buy Sea Chem Purigen and run it in your filter as well as pouring some seachem prime in there. Also do a large water change before you add prime into the tank.

Ammonia - 0

Nitrate - Less than 7 (it suggests this can go up to 50 before a water change is needed)

PH - 7.5

Liquid tests from Nutrafin

Tank temp is about 76F

Tank has been set up for 3 weeks and cycled.

Water conditioner is API Stress coat.

I'll do nitrites now, thanks for helping

Treated the tap water per whose instructions?

Does your tap water source exhibit chlorine, chloromines, heavy metals?

Did you test the tds of the original tank water versus the new water?

Was your tank ever mineralized or adjusted for kh/gh to begin with? Having them live for less than a week isn't any mark of success, while their deaths may have occurred within the next 24-48 hours if none of what was forementioned in my post was considered nor addressed. In fairness by assuming the plant or water change was the cause of death, you may even consider the possibility that the tank was not an ideal setup to begin with.

Being super busy for several days doesn't imply that they would be indefinitely without attending to their needs and requirements for survival.

Post more information if you require assistance.

You just 'rinsed' the plants in water??? I quarantine all my plants for probably a week or so before they go into the tanks and they get either a bleach dip (19 parts water to one part bleach, only if the plants can tolerate it, some can't) or an Alum bath or a bath in potassium pomegranate. Then they sit in dechlorinated water (heavily dechlorinated at that) for 5-7 days with water being changed out every other day. If they just started doing this when you added the plants that would be my first guess and I'd get those plants out of there as soon as possible and quarantine them and do another water change to be on the safe side. All the water changes are going to stress them though, just so you know.

The nitrite tested ok according to my test kit, ever so slightly pink, so around 0.1 on the Nutrafin chart that comes with it.

I washed and rinsed my hands before I started.

Thanks bananariot, all the shops are closed now : /

I treated the water according to the instructions on the bottle.

I do not know if the water contains these things and do not have a tds meter (yet).

No the tank wasn't mineralized or adjusted for kh/gh.

Thanks ravensgate, I hadn't read about this level of quarantine for new plants. I will read more on it and practice this in the future.

Quarantining plants is just an absolute must to me. I got a batch of plants in not too long ago full of bugs, critters, worms and about 50 baby pest snails. None of which I wanted in my tank. And then there is always the concern with pesticides. It's kinda scary adding new plants if you ask me. But I love the look of live plants so I just try to be as safe as I can. Hope you can get everything sorted out!

I would definitely at least soak the plants in some water for a couple of days. There were a couple of articles here on the forum about plants killing shrimp because the farms they were raised on had used pesticides. I think I can dig them up if you'd like.

If nitrites are showing up at all.. it can be a sign that the tanks not fully cycled.. how did you cycle it?

I would do a large water change 50+% it will cause stress but stress is better than death

Treated the water according to the instructions on the bottle of what? 3 weeks is a pretty short cycle. Shrimp are more sensitive than most fish, so they will be the first to go during an ammonia or nitrite spike.

The poster has already stated they used API Stress Coat.

Yeah Nitrites and ammonia are extremely deadly to shrimp. So there's something amiss if you got nitrites......

Thanks ravensgate, I will read about it

Thechiba, that would be much appreciated, thankyou.

rreekers, I cycled my tank with a baby snail, some marimo balls and some frogbit and I added some API Stress Zyme twice to help boost the process. I let this run for 2 weeks and tested with a nutrafin mini master test kits. There was no ammonia or nitrites and some nitrates (7.5 on their scale, 50 needing a water change).

I've done a 50% water change, thank you so much for your advice. I will report back in the morning.

livingword, hiya, I used API Stress Coat.

I know that I am new to shrimp keeping, but they seemed fine to me, until I did this water change and added the 3 plants, within an hour of that, things started to go wrong.

So far none have died, and the one that looked the closest, is a bit more active.

Hopefully they will all pull through as they all rock

Unfortunately, your tank isn't cycled if you're seeing Nitrite.

A "baby snail" definitely doesn't produce enough waste to cycle a 30 litre/8 gallon tank. Not even for ten Cherry Shrimp.

If you can't rehome those shrimp until your tank is cycled, definitely do massive water changes, as previously recommended.
