Found something like flea on the surface of the water, around 6 to 8 and very tiny? Cn someone help to identify and is it harmful?

Impossible to see. Can you get a better camera?

Oh yah, I had a handful of these in my bucket of NSW last month too. I bought too much water, so I left them in a covered bucket with a powerhead running.

2 weeks later when using the water, I found these black/brown bugs in the water, quite a lot of them. It's not some bugs that flew in, that I know for sure, cos they appeared in a sealed jerry can as well. Looks like sesame seed

Are they alive? how do they move? do they look terrestrial or aquatic?

Actually, they look terrestrial, doesn't look like any marine creature I've seen. Kinda like bed bugs. All dead and settled at the bottom. I'm quite sure they grew or bloated from the water cos the jerry can was sealed, nothing inside the water when I first brought it home.

They are alive when I fish them out of the tank, not sure how they look as it is really tiny but do like a flea, shape is like a beetle bug....

Hmmm.... well... throw them out. Maybe they got into the water somehow accidentally.
