they are pretty sensitive(Should not have rush in to add them), especially to PH. What shrimps you bought?
Care to share your tank specification? related topic had discussed before, perhaps you can browse a few.
My fishes are living great and healthy but for some reasons my shrimps suffers big loss.
To date, I've bought 3 batches of shrimps (7-10 shrimps each batch) and now they are all dead. That accounts for over 20+ dead shrimps.
Perhaps they are not used to a new 2-weeks tank? Or they are too sensitive to temperature or pH change?
What are the main reasons for shrimps to die fast in a tank?
Let me know so that I can rectify it.

I agree. Do provide us more detail of your tank. eg.type of substrate, it would also create an unsuitable pH, which shrimps are really sensitive to
metals? the manner in which they died could have provided some hint of what caused their demise.
taikiat? could you elaborate what you meant above? First time coming across such statement? manner of how they die?
in some cases, the shrimp swims around and around, then die, and it was likely to be heavy metals present in the water.
in other cases, the shrimps just appear cooked, or only their shells are left, then it could be a problem of ph, or ammonia.
all these are based on what i've seen on this forum, not my own experience in rearing shrimps because i don't have them. i'm still a newbie so please don't flame me if the above is wrong.
I've got Yamato Shrimps. I was told that they are much more durable. But then.... They still die...
A few of them were swimming around like mad-fish and slowly they swim backwards and then die. I think they are struggling with the sudden change in pH. That's my fault because I tried reducing pH from 7.4 to 7.0.
A few of them look very normal, then they die without any signs of struggling. No change of water, just die.
When they die, they are orange in color, curled up. Look like steamed drunken prawns. Now I don't feel like eating prawns.
BTW, how do I test for metal?
how you go about lowering the ph level?
for now, just continue cycling your tank.

Oh... you mean pH7.0 is not enough?
In my last tank, my 6 Yamatos are alive and kicking at pH7.8
Perhaps my new tank is TOO NEW for the shrimps? It's exactly a week old.
i really think temperature is impt.
never rush into keeping them, until u can manage to get the suitable env for them to stay.
cos when they start dying, u will feel more disappointed.
My yamatos also died recently when I added aquasoil, some new plants and new fertilisers to the tank. So I don't know what really caused their death. That was over a month ago.
Then I bought a new batch and they all died within the first week. So I have stopped using the liquid fertiliser (maybe I overdosed), and hopefully the next batch will survive. The tank is not new, was setup nearly 2 years ago, except for the new recent changes. It should be stable now, I hope.

metals are tested by test kits, i dunnoe if a 0.4 fluctuation is a lot, but 7.0 ph should be alright for shrimpsOriginally Posted by nkthen

BTW, how do I test for metal?could be metals if they swim like crazy, but must confirm with the hei bi pros
if i'm not wrong adding aquasoil could screw up the water parameters pretty badly, and aquasoil is known to lower ph for plants. ferts could also be the reason because some ferts apparently contain metals too. gotta check
oh my god..how many did you buy in a batch?Then I bought a new batch and they all died within the first week.

hope it is not alot..

it's certainly pH. Adding aquasoil would swing your pH right down to a 6. Your shrimps will definitely suffer a pH shock.
Do a pH test, it should show a result of around 6.
i would advise you to stop adding shrimps. Do regular water change for your tank, maybe 30-40percent for every 2days interval.
The same happened to me before and it took me painfully 1 month before i can start adding shrimps into my tank.
NH3/NH4, KH and GH differences (Osmotic shock) from the water that they came from probably killed them and not pH. I really don't know why you folks always go after the pH since it changes throughout the day due to gas exchange or CO2 uptake by plants. (pH goes up when it happens.).

Peter,
Sorry for the mistake. But it was from my personal experience. I ever heard from Mr Chan claiming that adasoil is not too good for shrimps initially due to it's pH (i might have misheard it).
My shrimps all died within my first month of my tank. It was only after regular water change, that i noticed quite a fair bit of change in pH, which later allows me to sucessfully introduce shrimps into my tank. But again, it could be the amonia build up initially

The big three problem I hear about are "Copper, Nitrates and Temperature changes" so be careful to avoid all three.
I don't know the reasons... I'm checking the solutions that I've put in side.
I've put OTTO's PSB Bacteria solution last week. I have AZOO's Water Softener in my water last week too.
Will that affect?
I also faced the same problem, when I start introducing cannister CO2 into my 3ft tank. 2~3bps from a DIY 0.5~1bps.
The shrimps are as though making sommersault in the water, struggling to keep their stand. In the end, they died, looking exactly like cooked prawns.
Somehow, I feel that the PH swing is too much for shrimps. They need to be acclimatised to the tank environment slowly.

can somebody help me? it seems that only my cherry shrimps are dying... i have blue shrimps, tiger shrimps, yamatoes and cherries in the same tank.. but last week 2 cherries died, this weekend 2 more died and today another 2 died... all looked very cooked... its not temperature as its quite cool... stopped CO2 yesterday.... i have no test kits and never relied on test kits before....
EDIT: Please avoid using sms language... There are so many short forms just now and it makes reading difficult... Thanks.
