There may be ways to help this improve for the long term as well. You do not describe the habitat of your betta. Small bowls are virtually impossible to maintain. Aquaria need surfaces for the bacteria to colonize. These are found in filter materials but also any other surface in the tank including substrate and decor.
Please provide a complete description of your setup so long term care can be helped. After all, you now have a living thing that is your responsibility.
