Anyone can tell me what is the lifespan of shrimps (yamato, malayan, bumble bee etc) in general?

I never have luck with long living shrimps to date.

i think its due to acclimazation process

**hatchet** · 16th Oct 2002, 17:56

Hello Simon,

when you say acclimatization, you mean the temperature of tank in general or when introducing the shrimps into the tank.

Or can it also be the water conditions. I have checked my PH, its 6.5, my KH is usually at 4. My nitrate levels are almost non existence.

What other test should I take further? Ammonia, Phosphate, Nitrite etc??

thanks

u have to bring the water parameter in the bag to that of yr tank.. plus they need time to acclimatize.. usually, i will float the bag in my tank for 5mins, and at every 10-15mins interval add tank water into the bag till u get 100%... oso yamato (dunno how other shrimps) sensitive to nitrate lvls and some to high temp.. above 30..

Thanks Simon,

One more question, Whats the difference between Nitrate and Nitrite?

**Simon** · 16th Oct 2002, 23:50

LOL.. u asked the wrong person abt No2 &amp; NO3... i know nutz.. perhrps some of the guys can explain

----------------
u first need to understand where u get NO2 and NO3..

To get nitrite NO2, u first will get ammonia which is generated from the wastes of the fishes and the biological bacteria, assuming that your filter is up and ready, will become home to aerobic (oxygen-loving) bacteria called Nitrosomonas, which will consume the ammonia and produce wastes products called NITRITE.

NITRITE is then consumed by other bacteria called nitrobacter which will then produce a less harmful wastes called NITRATE. and nitrates are taken by plants or algae in marine... the oxidation by the anaerobic bacteria will cause nitrogen gas to be released into the atmosphere.

This is what they called, Nitrogen Cycle. me dun know whether have i answered your qn.. but at least i tried..

kel and Simon, thanks for helping me out with those questions.

Normally how do you guys remove no2 and no3 other than frequent water changes?
Should I also test for phosphate......and where do I get phosphate..... and how do i remove it also?

If my nitrate level is low, does it mean my nitrite level is low also??

Funny and frustrating thing happen yesternite, I release some yamatoes into the tank, after a while i caught my big SAE attacking them......even some legs kena eaten......sigh...

Hatchet..nitrate is the last by product of the nitrogen cycle other than the nitrogen..LOL..hope i got it right. If your nitrate is low..I can safely say that your nitrite is zero. [

] ..Other ways of lowering your nitrite level is by having healthy plants [

] ..they consume nitrite along with other nutrients during photosythnesis period. Phosphate comes from fish food and decomposing stuff I think...not very sure though..but must be one of them or both. Hope that helps.

if you have high levels of nitrite
DO WATER CHANGES IMMEDIATELY
you should never see &gt;0.2 unless your tank is newly setup
no2- kills at &lt;0.5 ppm

as for your shrimp problem
your filtration is not good
if your tank is heavily planted, your shrimp should have no problems
clean out your filter, i suspect a high accumulation of crud inside

To clarify something.

Low nitrates means low or zero nitrites only applies for matured tank with healthy nitrifying bacteria colonies.

If the tank is new or there has been a die-off of the bacteria colonies (e.g. after medicine treatment), it probably means that there is not enuf bacteria colony to convert the nitrites to nitrates.

And... plants do not consume nitrites.

You are right about reducing nitrites by having healthy growing plants (lots of them). They do it by consuming the NH3 before they get converted to NO2.
