None. The 1 gallon bowl is already too small for the betta by itself.
they can live in goldfish bowls i have always kept my beta in a goldfish bowl and my last beta lived between 4-5 years in a goldfish bowl.
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
yes.
Goldfish dont have to have a filter but they need water conditioner like all fish.Fish can survive without a filter but they are always good to have because you dont have to clean it out as often
I am no expert, but believe that betas are solitary and prefer to have a fish bowl to themselves.

the betta fish is a very beautiful fish but maybe put them in a seperate bowl for awhile.
A betta fish is the only fish that can stay in a bowl :) hope I helped :)
