Can a fire belly newt live with a Betta?

Please do not attempt to mix amphibians with fish. It can not, and will not be successfull. They require totally different temperature ranges to live in and the newt will poison the water for the Betta. The basic rules of sucessfull fishkeeping are. :- 1 inch of fish needs at least 1 gallon of water.(a Betta needs at least 3 gallons heated to around 78F) :- Every tank must have a permanently running 'cycled' filter. :- Every tank needs at least 50% of its water replaced every week. Follow the above and your fish will stand a chance of survival. Fail to follow them and I can guarantee that your fish will be constantly getting sick and will live a shortened lifespan.
