It is natural for fish to swim in any direction and and at night time when there is no light from the moon they go into direction in surfaces where artificial light is present. Their biological requirement for oxygen directs them to swim counterflow to the source of current that is normally loaded with high amount of dissolve oxygen .

Yes. Other fish do this behavior too. When there is more nutrients and food upstream they will go here. The also move upstream to migrate to breeding grounds.

Answer2: In addition to the other comment, I read such an interesting article on the brook trout. According to a study published in Science magazine, brook trout and other varieties of fish exploit turbulent flows swirling around stationary objects in the water to minimize effort and give themselves an energy-saving boost current. By alternating their body position and synchronizing movements with the eddies they encounter, says New Scientist, trout save so much energy that they do not have to use their main swimming muscles." It's a very low-energy way of moving through a turbulent environment," explains one of the authors of the study George Lauder, a biomechanician at Harvard University. In effect, says New Scientist, "the fish were bending their bodies into wing-like hydrofoils to catch the eddies, like a sailboat tacking upwind.

All fish swim downstream at times just as all fish swim upstream at times. It all depends on where they wish to go.
