What filter should I use for my 3 gal Betta tank?

    Hello, I'm building a 3 gal Betta + plants tank. I would like to know what would be the best filter for this tank. Should I follow the 10x the volume rule for the gph? I've heard that Bettas dont like too much movement in the water so I'm worried that a filter like this might stress him out.

    What do you guys think?
