What do betta fish eat?

Bettas generally eat brine shrimp, bloodworms (tubifex), dried bloodworms, daphnia and mealworms, occasionally some dried vegetable leaves or green algae, and also commercial feed. Avoid feeding a single food long-term to prevent nutrient deficiency and immunity drops. Use floating-type food; don’t overfeed vegetable matter – feed 3-4 times a week in measured amounts.
