Transferred 6 cherry shrimp from my 330L to my 9L nano the other day.

They had been acting normally but am sitting at my desk now (tank is at my desk) and I notice there is an abnormal amount of movement.

They keep hooning all over the tank, swimming laps etc. Moving very fast.

Is this normal?

pH is 7-7.4
temp is 28

ammonia, nitrate, nitrite etc is minimal.

Tank had been running for 3 weeks before adding them. Feeding once daily.

Plenty of moss, hiding places etc.

Urgent assistance would be good - I might put them back in the big tank if this continues.

ammonia, nitrate, nitrite etc is minimal.

Minimal meaning what exactly.

[simmoman]

In a cycled tank Anka the ammonia and Nitrite should be zero not minimal.

[Anka]

I'm colourblind so find it difficult to distingush zero and just above zero.

No one is home to test for me

[simmoman]

apologies, forgot the colour blindness prob.

Got my sister to test:

pH 6.7
Ammonia between 0 and 0.25ppm (closer to 0.25ppm) <=========== I guess this is the problem?
Nitrite 0
Nitrate 0

Temp 26.5

I added some stress coat to convert ammonia to less harmful ammonia, should I do a water change? if so, how much?

FYI - water last changed Sunday when ammonia was 0!

I would retest the Nitrate as it is almost never 0. Before you test again be sure to shake the solutions very well as they can give you false readings if not shaken befor use.
I would do 50% water change.

[Anka]

50% change done

it might be males searching for a female that just molted and let her hormones off

autolink, can you please describe what normal behaviour is for cherry shrimp?

In the big tank they tended to hide in the plants and moss (there were neons in the tank).

Now they are all hooning in the small tank. Males and females.

[mandm]

This is a video of my shrimps behavior sorry about the quality :/ in the video it has shrimps hooning around is it the same as your tank ?

Its really hard to describe shrimp behavior.


Cheers Jake

[Anka]

similar - do yours pretend to swim to the top but never break the surface? they scurry on the walls of the glass at lightening speeds

[mandm]

yeah mine are doing it right now same with my Crystal reds and blacks they are all flying around they tend to slow down to once they find there is no danger in the tank.

Cheers Jake

btw awesome tank

Doesn't look unusual to me, this is normal cherry behavior.

It is more common to occur when gravid females are ready to mate.

FYI - a female carrying eggs died, as did 2 others

If your ammonia and nitrite are 0 then I suggest checking for copper.

Extreme doses of glut (excel, dino spit) can also also slowly kill them.

Alternatively poorly regenerated purigen/macropore and similar products can also slowly kill off your shrimp. (as will not using a dechlorinator/water treatment on tap water and or using a poor quality water conditioner.)

Cherrys are fairly difficult to kill Normally, slow die off suggests an underlying long term issue.

Small spikes caused by insufficient or not properly cycled tanks will also knock em off. Even if readings are 0. Check your oxygenation as well to ensure good exhaust transfer of toxic compounds and gases.
