Yes, I use 2 nets too but even 1m wide nets aren't as effective for very fast fish. You can also try a gate net which is 2 rectangular frames with a hinge joint in middle. On a circular tank, just corral the fish into a smaller and smaller pie shape section by moving the sides closer and closer together. . On a rectangular tank, use as a straight fence initially, then bend as needed.
Do need to be careful, one large jumping fish broke my collar bone. Polarising sunglasses helps see through the surface glare.
