If you're sticking with a 5g or 10g I would go with an assortment of male guppies/endlers.
There is a bunch of colors for her to pick from and they'll provide a lot of "action"; you can even throw in a nerite snail as an "oddball" addition.
Let her pick her favorite colored gravel and even an air powered bubbler toy (spongebob/pirate, etc) and she has a nice little starter tank.
