Hi,

I found these ugly little guys in my aquarium, can anyone tell me what the are please?

 

[ar0wan]

looks like copipods. Good source of protein!

 

[BobCat]

They are nothing harmful then?

 

[Oddball]

Not harmful. Cyclops are a great early food for small fish.

what kind of camera is that
and how much is the zoom

 

[BobCat]

The pics are taken with a microscope. Thats 40x zoom.

I bought the microscope before Christmas for £90 in a cheap supermarket promotion. Never used it until I posted recently trying to describe what I could see on my aquarium glass and I remembered it was in the back of my cupboard.

Dang, nice pics. Those will naturally appear in your tank. Fry will eat them if your fish are breeding. They are also part of the reason why a lot of peeps like to keep "dirty tanks" for raising fry, cause a lot of those microscopic things tend to thrive in that type of environment so that the fry can have living food 24/7. Resulting in better growth rates.
