Feeding Siamese Fighting Fish (Betta splendens) requires an understanding of their dietary needs, which can differ from other aquarium fish. Here are some essential guidelines for feeding: 

Dietary Habits: Betta fish are naturally carnivorous. In their natural environment, they primarily feed on insects and insect larvae. 

Species-Appropriate Feeding: A balanced diet for Betta fish should be rich in protein. Special Betta fish foods are available in pellet or flake form and contain the necessary nutrients. Ensure the food is small enough, as the mouths of Fighting Fish are relatively small. 

Live and Frozen Food: For variety and to encourage natural hunting behavior, live or frozen food like mosquito larvae, daphnia (water fleas), brine shrimp (Artemia), or small worms like Tubifex are excellent. 

Feeding Frequency: Ideally, feed your Betta fish once or twice a day, providing only as much food as the fish can consume within two minutes. Overfeeding should be avoided as it can lead to health problems and impair water quality. 

Control Portions: Siamese Fighting Fish have a relatively small stomach. Therefore, small, frequent feedings are better than large, infrequent meals. 

Fasting Days: It can be beneficial to have a fasting day for your Betta fish each week. This helps prevent digestive issues and ensures the fish is not overfed. 

Caution in Community Tanks: If your Betta fish lives in a community tank, ensure it has access to food and is not hindered by faster fish during feeding. 


Your Siamese Fighting Fish’s diet plays a crucial role in its health and well-being. With a balanced diet consisting of high-quality dry food and supplemental live or frozen food, you ensure that your colorful companion receives all the necessary nutrients. Remember to adjust feeding amounts and diversify your Fighting Fish’s diet. This way, your Betta splendens can lead a long and healthy life in your aquarium.
