Hope your son enjoys his new fish and welcome!
But i worn you. People call Bettas "easy to care for pets" because they dont need a filter (but still a heater). They do not need an air pump because they are able to breath from the surface. But since they dont need filters they need regular water changes, (about a full change every week depending on size of the tank).
Also it is best to give him a 5 gallon min if it is not filtered or a 3 gallon min if filtered.
Also, the water needs de-chlorer (sorry if i spelled that wrong) to remove chlorine and harmful heavy metals in the water.
And have fun! (if you give him pellets you can try making him jump for food! Its a good way to keep your fish entertained)
