What happens when you eat a betta fish?

Eating a betta fish is not recommended and can be harmful. Betta fish, like many other aquarium fish, are not meant for human consumption and may carry parasites or diseases that can be transmitted to humans. Additionally, betta fish have small bones that can pose a choking hazard. If you are interested in consuming fish, it is best to choose fish that are specifically intended for human consumption and are safe to eat.
