Betta fish, also known as Siamese fighting fish, are celebrated for their vibrant colors and flowing fins. To maintain their health and vitality, providing them with an appropriate diet and environment is crucial, differing from the needs of many other common aquarium fish. This article will explore the dietary needs of betta fish, covering what to feed them, how often to feed them, and solutions for when a betta refuses to eat.
Understanding Betta Fish Dietary Needs
Betta fish are naturally carnivorous, consuming insects and insect larvae in the wild. Understanding these natural feeding habits is key to replicating a healthy diet for your pet betta.
What Betta Fish Eat
As carnivores, betta fish require a diet rich in protein. It's a misconception that bettas can thrive solely by nibbling on plant roots in a small tank; this is detrimental to their health.
- Betta Pellets: High-protein betta pellets should form the foundation of their diet. It is essential to use a pellet formula specifically designed for bettas, as those intended for other fish species may lack the necessary nutrients. Quality betta pellets and flakes are formulated to provide the correct balance of nutrients, and they are easy to portion, which helps prevent over or underfeeding.
- Treats: High-protein freeze-dried and frozen foods like brine shrimp and bloodworms can be given as occasional treats. However, these should not constitute the majority of their diet and should be offered in moderation.
- Live Foods: Live foods are highly recommended because they closely mimic a betta’s natural diet. Live blackworms are a great option because they can survive in the aquarium for a while without polluting the water. However, they may carry parasites and aren’t always available in local fish stores.
How to Feed Your Betta Fish
The general recommendation is to feed betta fish two to four pellets once or twice daily. Pellets expand when they absorb water, so portion control is important. Freeze-dried or fresh food can replace pellet feedings one to two days per week. Uneaten food should be promptly removed from the tank to prevent water quality degradation.
Cost of Feeding
The cost of betta fish pellets and freeze-dried food varies by brand, typically ranging from $4 to $8 per container. Buying in bulk may be an option for cost savings.

Live Food Options for Betta Fish
Bettas thrive on live, tasty treats like worms, crustaceans, and small insects. In their natural environment, mosquito larvae are a staple, though sourcing these can be challenging for aquarists.
- Mosquito Larvae: If you find mosquito larvae in water, ensure the water is clean to avoid introducing diseases into the tank.
- Microworms: Microworms are easy to culture and are a good source of nutrients for baby bettas. Culturing is simple, with the first harvest possible in 3-4 days. Reserve some worms to maintain a starter culture. Mini-microworms, or waterworms, are smaller versions of microworms.
- Brine Shrimp (Artemia): Brine shrimp are rich in essential nutrients. Some betta owners establish their own shrimp hatcheries to guarantee the quality of the live food.
- Daphnia: Daphnia, found in small pools and ponds, were once considered the best fish food. However, wild daphnia can introduce diseases, parasites, and toxins, making home cultures a safer alternative.
- Bloodworms: These are midge fly larvae, with their red color due to iron-containing porphyrin. Bloodworms contain 6-8% protein and are a natural iron source. Since they lack certain essential amino acids, they should be supplemented with other nutrient sources.
- Earthworms: Often overlooked, earthworms are excellent protein sources. They can be collected from a backyard or purchased from a bait store and stored in a jar in the refrigerator.
Human Foods as Occasional Treats
While high-protein betta pellets should be the primary component of a betta's diet, certain human foods can be offered sparingly as treats. Betta fish thrive on protein-rich diets, so these foods should not be the mainstay of their nutrition.
- Leafy Greens: While not all vegetables are beneficial, certain leafy greens like lettuce and spinach can provide additional nutrients lacking in pellets.
- Peas: Boiled peas (without the pod) are a safe and digestible option.
- Apples: Apples, cut into tiny pieces, can be a sweet and enjoyable treat, but should be given sparingly.
- Sweet Corn: Boiled sweet corn (one kernel at a time) can be offered, but it is not particularly nutritious and should be given very conservatively.
- Cucumber: Blanched, seedless cucumber, cut into small pieces, is another vegetable option.
- Mango: Remove the skin and pit, and cut the mango into very tiny pieces.
- Pears: Ensure the pear is soft, remove the skin, and cut it into tiny pieces before serving.
- Strawberries: Cut the fruit into very small pieces.
- Cantaloupe: Only serve tiny portions of the orange part of the melon, avoiding the seeds and rind.
- Egg Yolks: Boiled egg yolks, dried and served in chips, are a protein-rich treat suitable for betta fry. However, be cautious about overfeeding, as they can easily contaminate the tank if not prepared correctly.
- Seafood: Shrimp and scallops, cut into tiny pieces (avoiding shells), can be given as an occasional treat.
- Chicken: Boiled, unseasoned chicken, cut into small pieces, can serve as a protein substitute on occasion.
Important Note: Citrus fruits should never be given to betta fish due to their high acidity, which can be harmful to the fish and the tank environment.
Addressing Feeding Concerns
Two common issues in betta fish care are overeating and undereating.
What to Do If Your Betta Fish Will Not Eat
Betta fish can survive without food for up to 14 days. If a betta skips a meal or two, it's usually not a cause for immediate alarm. Potential reasons for a betta's refusal to eat include:

- Stress: Recent changes in water temperature, tank cleaning, or environmental changes can affect appetite. The ideal water temperature for bettas is between 71 and 86 degrees Fahrenheit.
- Inadequate Tank Size: Small bowls can make bettas unhappy and unwilling to eat. Ensure the fish has enough space to swim and explore.
- Food Preference: Experiment with different pellet brands if the fish turns away or spits out food.
- Age: As betta fish age, they may become less active and consume less food.
- Illness: If the betta continues to refuse food, it may be ill, requiring veterinary consultation.
How to Prevent Overeating
In the wild, betta fish eat whenever food is available, making them prone to overeating in captivity. Overeating can lead to bloating, digestive issues, and obesity. Excess uneaten food can also pollute the tank water. To prevent overeating, stick to the recommended daily amount of food.
Alternative Food Options
- Freeze-Dried Foods: Freeze-dried tubifex worms and brine shrimp are good alternatives to frozen foods. They don’t require freezer storage and tend to float on the water’s surface.
- Fluval Bug Bites: These nano pellets are made primarily from black soldier fly larvae, closely mimicking a betta’s natural insectivore diet. They are rich in quality protein and essential vitamins and minerals.
