Does the Siamese fighter need a airstone in the tank?

Siamese fighters (Betta fish) do not necessarily require an airstone in their tank, as they are labyrinth fish and can breathe air from the surface. However, providing some water movement with an airstone can help improve oxygen levels and enhance water quality. It's essential to ensure that the water flow is gentle, as strong currents can stress Betta fish. Overall, while not mandatory, an airstone can be beneficial in certain setups.
