Yes. They don't necessarily need to be up there all of the time, but every once in a while, they need oxygen. If they are at the top of the tank a lot, that's okay as well. In conclusion, they should go to the top of the tank regularly so that they are able to breathe.
Siamese fighting fish Thailand
Bettas, also known as Siamese fighting fish, are native to Southeast Asia, living in shallow waters such as rice paddies, streams, and ponds. They prefer warm, slow-moving waters with plenty of vegetation to hide in. In the wild, bettas can be found in countries like Thailand, Cambodia, Vietnam, and Laos.
Siamese fighting fish prefer water temperatures of 24-30 degrees Celsius, or 75-86 degrees Fahrenheit.80 degrees or so, they are tropical and live in rice patties through out Asia. They should have a heater in tank and not be kept in tiny glass bowl at least a 5gallon tank would be best with at least 3 femal bettas
When on any boat you should always be wearing a life preserver vest. The first thing after a board capsizes is to seek the waters surface. There may be an air pocket that forms inside the overturned hull that will let you get your bearings as to where you are and how to best get to the waters surface. Stay calm and do not panic if at all possible.

Surface waters of the Earth are typically referred to as "water bodies" or "water sources," which include oceans, seas, rivers, lakes, and streams. These surface waters play a crucial role in supporting various ecosystems and human activities.
Ponds and lakes typically undergo turnover in the fall and spring. In the fall, cooling surface waters sink and mix with deeper, oxygen-rich waters. In the spring, warming surface waters mix with cooler, nutrient-rich waters.
Upwelling carries nutrients out of deep ocean waters, which are typically cold and rich in nutrients due to the decomposition of organic matter. This process occurs when deeper waters rise to the surface, often along coastlines or in areas where winds drive surface waters away. As these nutrient-laden waters reach the surface, they support high biological productivity, particularly in marine ecosystems.

Upwelling is the ocean process that brings vital nutrients from the bottom to the surface waters. It occurs when cold, nutrient-rich waters from the deep ocean rise to the surface, fueling the growth of phytoplankton and supporting a vibrant marine ecosystem.
