help! yamoto shrimp playing dead. < Close this post>

[freezze]

Anyone encounter this b4..
last nite, i planted afew plants into my tank.. after a while, all my yamoto started to go berserk .. swimming all over the tanks.. after a while, all of them drop like fly.. n play dead...

i fished them out i place them into a bucket.. after a while .. all of them start to move about..

issit the plant i placed in have some chemical that the yamoto cannot tahan? but all my fish r ok.. still healthy n swimming

[prec]

i faced this problem in the beginning stages of my shrimp tank. they swim everywhere after i put them in after proper acclimazation. after a day, they start to die. not play dead. some were like struggling and falling on the gravel. and i scoop them up into my glass betta tank and within 10mins, they seem as healthy as ever.

the problem: water quality
the solution: change 40% water and let it run for 2 weeks before putting in the shrimps again. make sure ur tank is heavily planted.

thankx i try that n c whether they can survive...

I posted this before... the reason is poor acclimatization. The shrimps swimming frantically - means the water quality does not suit them well(least they have get used to it). Leaving them there...they will soon die.
Introduce the shrimps to your tank slowly...many threads talking abt introduction of shrimps to tanks.

Below is what i posted regarding shrimps dying....
"In summary, poor acclimatization and temp tend to be the no 1 factors. (least what I think). As in all fishes, you need to introduce the shrimps to the tank and trust me, they need longer acclimatization compared to fishes as they are vulunerable. The other factor is temp. In general, shrimps tend to do better at lower temp.
Some tips(learnt from real experiences)
1. Observe the shrimps before you buy them. In bulk, look at the behaviour of all the shrimps, R they swimming about(if so, not gd)? R their bodies milky white(bad - lack of O2)? , R their colours good(good colours means stable)?
2. Feel the water/temp of the package. Most of the time during transportation, these package are subjected to higher temp.
3. Transport your shrimps in cool and safe(less shaky) conditions
4. Have a longer acclimatization timing.
5. If the shrimps start to behaviour oddly(springing around, swim up and down), net them out and put them back into the original water (always scoop some package water out from newly bought fish/shrimp - it has always been my practice) "

the shrimp was doing fine until i added new plants in.. thy been living in the tank for over 2 month.. so the water should be no problem .. rite?
donno why but after i add some more plants in , thy just went n play dead...hmm (maybe thy do not like how i deco the tank... )

anyway i change 40% of the water n wait for a while b4 i place them back in..

R there any plants that give of some kind of chemical that the shrimp cannot tahan or dislike..

im not so sure that plants giving out chemicals. but do not put your shrimps in after such a large water change as the water is not so stable for them yet. put them in after a few days.

Encountered this before. Quite sure it is due to the chemicals from the plant. Some plants are heavily fertilized in the shops, especially moss. Make sure that you waste them thoroughly and maybe soak for a few days.

water change may not be a good idea....shrimps don't like major water change..

I ever put in a bunch of moss and _all_ my shrimps died in one night.

Perhaps...not sure abt plants giving out chemicals..never hear before as well... but maybe on a case to case basis...(excessive insecticides on vegetables?)...maybe the plants need to be wash and quarantine as well...haha(not sure)
I think its the natural cycle of a bio system. There is really logic/reason that tanks are setup with plants and running for 2 months before fishes n lifes are introduce... if not, tendancy that there will be some casualties...
Anyway back to the main point, how big is yr tank? I was once told by an expert that large tank(4ft) are easier to manage. I was in doubt when he mentioned that...my impression has always been 2ft easy to start and maintain. His reasoning - large tank has a bigger buffer for water/cycle differences. ie the slight change in water/O2/CO2 maybe not have great impact as compared to a small tank...

mine is 3ft tank..

anyway i placed on of the shrimp to c the behaviour.. hopefully can..

There is strong possibility that the plants may be the cause of the shrimp's reaction. LFS tend to stock plants with projection of selling them within the next few days, so most of the plants would come prep from farms. Dunno about all the farms but I know some of them using commercial agri ferts and snail killers. Traces of these can hurt our shrimps.

If you have a lot of shrimps, you may want to quarantine your plants in other tanks before planting. That may reduce risk.

after this few day..all the yamoto are still alive.. but nowaday they are not so active..
before this incident, all the yamoto would swim to the surface whenever i feed the fishes.. now thy just stay at the bottom or out of sight..

this will mean that they are not very happy shrimps.
