Do betta fish do well in round places?

Betta fish can be kept in round tanks, but it's generally not ideal. Round tanks can create difficulty in maintaining water quality and temperature, and they may limit the swimming space for the fish. Bettas thrive in environments that allow for proper filtration and space to explore, so a rectangular tank with a larger surface area is usually a better choice. Providing a suitable habitat is essential for their health and well-being.
