tank for a child

first The coment about owner responsive fish is the number one thing to keep her interest.
tank size a 125 on a custom stand around 12" would work nice tank depth is key 18" or less the 55 to deep.

Goldfish would be the right choise very owner responsive hearty and dont require a heater.
Also long lived dont need nemo kicking off in two months.
 
I'd see what she like, but for a tank that big I'd for a couple of largish cichlids that are going to hang around and grow up with her for some years.
Small colourful fish are alright, but they don't hold my sons attention for long
 
When we go to the store, the fish she always migrates to are the ones listed in the post. I don't want to tell her "no you can't have the ones you really want because I think you'll get tired of it". I already dissuade her from getting fish for the other tanks in the house that aren't owner responsive. We already have cichlids (though I want more) and we plan to have goldfish in a tank in my hallway. I'm sure she will have the tank long enough that she will get to change her mind later, but she really likes small things and detail and color. I don't think she'll get bored with it quite as quickly as you think. This is a child who can play with a handful of marbles or rubber bugs for hours on end because of all the stories she makes up about them. The main thing though is that she gets to be involved in what she chooses to get, and to learn for herself what she does and doesn't like.
