Just finished a water change on my 300l community tank and I discovered tiny bugs floating on the surface, they looked dark brownish and they jumped! really suprised to see them as I thought the fish would have eaten them, just dont know what they could be.

?? I am wondering if they were under the lip of the tank and got washed in as I was re-filling the tank, fish have eaten them by the look. The nearest thing I can find is some sort of aphid?? I do have a potted plant on top of the tank I wonder if there is something in the soil in the plant and they have taken up residence under the hood of the tank.
