That is entirely up to you. Whichever fish you get you will need similar things. The differences are. A Goldfish is a coldwater fish. It will need a larger tank and filter than a Betta because it grows into a much larger fish (around 10 inches). A Betta is a tropical fish and so it will need a heater as well as a filter. The same basic rules apply. The basic rules of sucessfull fishkeeping are. :- 1 inch of fish must have at least 1 gallon of water. (Goldfish 10 gallons. Betta 3 gallons):- Every tank must have a permanently running 'cycled' filter. :- Every tank must have at least 50% of its water replaced every week. If you keep the above rules your fish can do well. If you fail in the above I can guarantee that your fish will get sick and die way before they should.
Betta fish are best as a solitary fish and are not compatible with goldfish.
It should be fine.
yes because once i got a betta fish and i put in a tank with a gold fish the first day the betta killed the goldfish so i boult a nother goldfish it did not kill the goldfish because i put them in sepret tanks so that's what you guys should do it because i did it try it people your goldfish will not dy. my goldfish was a fin-nipper that's why it killed it because the goldfish ripped a fin off of the betta so do not put betta fish with goldfish because you never no if the goldfish is a betta.
