Help for kid (13) with 50 gallon tank - easiest fish for him

[GingerBaker]

So my brother decided to buy my nephew a fish tank after over a year of asking. Why 50 gallons? It's my old one that I used to grow out betta fry.

Anyway I am asking for suggestions on easy fish for a 13-year-old to look after for a 50-gallon tank. He's responsible & all but at the same time he's 13 and I don't want fragile fish that'll pass away if the water's not changed for say two or three days extra (his dad won't let it sit there but dad's working).

Platies, zebrafish, most larger tetras, and most barbs, but not together.

Some guppies or other live bearers Kids always love it when their pets have babies.
