tiny 1 to 2 mm black round thing in plants

[bensonchong]

Hi all,

I wonder if anyone come across this tiny creature that swim around the plants. They are about 2mm size and round. Also wonder if fishes would eat them and clear my tank.

Thanks

are they cyclops ? its ok to have them, fish loves them...

Is it seed shrimps? Cannot be cyclops, cyclops are too big for 2mm.

Fishes do eat them and only when they are hungry

Copepods and seed shrimps tend to be white or light colored... if the little critters are black color, then they might be mosquito pupa, the last stage of its development before they turn into mosquitoes.

Do you have any small fishes in you tank?
