84 shrimps in a 30cm by 20 cm by 20 cm tank

Is it overcrowded?
what will be the effect?

Thanks

The effect will be that the jump out :D

Joke , the waterquality sucks with that much shrimp.
Maybe they stop breeding then..

It is _way_ overcrowded. That many shrimp in such a small space will lead to water condition problems (e.g., nitrate/nitrates/ammonia). The bioload of all the shrimp combined will lead to shrimp deaths. And more than likely, even if you are able to get the shrimp to breed, the babies will die.

Hi,
yes these are too many shrimps for such a small tank, even if it is well planted and filtered. Reduce the number to about 20 till 30 adults and reduce the number of juvenile shrimps from time to time. With about 20 adults you should be able to raise up to 100 or even 150 shrimplets to juveniles in this tank. Then catch the juveniles or replace the adults with younger shrimps.
But if you overstock it, the mortality rate will increase significantly and the adults will stop breeding at a certain point. So better keep less but healthy shrimps in this tank than too much with only a few or no offspring.

Best regards

Robert

Ya you are very right that my cherries got orange eggs at their head... but never seem to lay the eggs... I waited for over 3 weeks already

however, My mosquito shrimps did lay eggs...

My ammonia is already at 0 ppm. Not sure why another 2 shrimp ( 1 bee and 1 unknown) died yesterday....
:(

Overcrowding affect the water parameters only?
What other reasons for shrimp not breeding?

Thanks a million!!

I once counted 600 cherryshrimps( in all sizes) in a 40x25 cm tank. Even that was not overcrowded! The water quality was just fine and the shrimps itself where healthy and happy.

As long there is good water and sufficient food and shelter, I don't think it matters. :) They are perfectly fine with huge numbers as long the above factors are there.

Hi,

i think it might be ok but water condition change fast with overcrowded tank.

Will be better to have a bigger tank/or few as it allow bigger error in tank unless u monitor the condition closely.

I agree with discuz. You could keep that many in a tank that size, but why take the risk? Fluctuations will happen a lot faster, and temperature swings could become more pronounced. Keeping them in a bigger tank will just make your life a little easier.
