Fish recommendations for a 5 gallon tank

I just bought a 5 gallon tank. I assembled it this evening, added the rocks, an ornament, the filter and a small pump for bubbles. It looks lovely enough and I'd love to keep it just like this, but alas... we bought it for fish (haha, can you tell I'm not a fish person!?)

I have young children, which is why I bought the tank- for them. I know I likely can only buy one or two fish with such a small tank- but I was curious what exactly I should buy to put in there?

I am, admittedly not great with fish. Several years ago I remember buying betas because they were pretty but one killed all the others.

But this time Im hoping will be different. I am hoping to buy hopefully two low maintenance fish. Recommendations, please?

A betta is very easy to take care of but you must not put more than two of them in the same tank. This is one of the most fundamental rules about betta-keeping...without meaning to offend, I do suggest you research the breed of fish you want to keep before buying one, before you bite off more than you can chew. (Too many people buy little plecos thinking they'll fit in their 5 gallon tanks, not knowing that plecos can grow huge and require 60 gallon tanks!)

I would definitely recommend a betta, particularly because you are buying the tank for your children. Keeping a small fish tank is a fun and effective way of teaching a child responsibility, but fishkeeping isn't as easy as it looks and very often, fish die from "beginner's mistakes". Bettas are extremely hardy, and will put up with most of these mistakes (note that I said *most*.)
