Tiny white bugs in my aquarium

[palendin]

Hi ALl,

 

i noticed these super tiny white bugs swimming around in my planted aquarium (there is no fish at the moment) .Does anyone know what they are and whether they are harmful to fish and/or plants?

 

Thanks!

It's very common to get little white bugs in your aquarium, especially if you have live plants. They're copepods, and are just part of the ecosystem.

Ah ok. thank you, i wouldve assume its part of the ecosystem, they always come back even after frequent water changes.
