Can Guppies Eat Betta Food: Everything You need To Know

Lots of pretty betta fish are swimming in a nice tank with plants and flowers. The words on the picture ask, 'Are guppies eating betta food?'

Keeping guppies in my aquarium brings color and liveliness. As a devoted fish keeper, understanding their diet is crucial.

In this guide, I unravel the question: Can guppies eat betta food? Guppies, omnivores, need vegetable matter, unlike bettas, carnivores.

While betta food may suffice, it’s not ideal for guppies. As a pet lover, I’ve wondered if betta food could substitute.

In this article, I explore guppies eating betta food. Their nutritional needs, and maintaining a balanced diet.

Settle in for this fascinating journey based on interesting facts together.

Understanding Guppy Dietary Requirements

Guppies, being omnivores, thrive on a diverse diet of plant-based and protein-rich foods.

In their natural habitat, they feast on algae, insect larvae, and small creatures. 

Although betta food may not include all the nutrients required, the digestive system of Guppies can manage a variety of diets.

Guppies require a combination of plant- and animal-based foods; although they can eat bettas food, this shouldn’t take the place of a regular, well-balanced diet.

I also noticed that Guppies can eat the food that you feed to Goldfish, which may tank mates for guppies. 

Through first-hand experience, I have come to realize that adult Guppies can go up to two weeks without eating.

Without feeding, guppy fry can be tolerated for roughly three days. 

To copy this balance in your aquarium, consider these ideal food options:

Flake Food:

Choose a high-quality tropical flake food, packed with essential nutrients and vitamins.

That will support your guppies’ growth and health. Another fish, Tetra also likes tropical flakes.

Frozen or Live Food:

Enhance their diet with nutritious brine shrimp, daphnia, and bloodworms.

These options offer diverse proteins, aiding guppies in growing well and staying healthy.

They support reproduction and a strong immune system.


Introduce blanched spinach, lettuce, cucumber, or zucchini to cater to their plant-based cravings.

These veggies add variety and essential nutrients to their diet.


Consider using small-sized pellets designed for guppies. These pellets serve as a practical choice compared to flake food.

This provides your guppies with a diverse and well-rounded nutritional profile.

This helps ensure their health and thriving well-being in your aquarium.

Variety is crucial in their diet, ensuring they get all essential nutrients. Option for high-quality food sources to maintain health.

Guppies, natural omnivores, evolved to eat small insects, larvae, and algae. Replicating this diverse diet is vital for their vitality.

Understanding guppy fish nutrition involves recognizing their role as omnivores.

It is crucial for maintaining ecological balance. Guppies are adaptable to various food sources.

They can consume both animal and plant matter. That is essential for a well-rounded diet while guppies are in a tank.

Analyzing Betta Food Composition

Nutrient Breakdown:

Betta food, formulated for betta spenders, boasts a crafted nutrient profile. 

Examining betta food involves looking at the breakdown of proteins, carbohydrates, and fats.

This analysis provides insights into its suitability for Guppy fish consumption.

Essential Vitamins and Minerals in Betta Food:

Betta food goes beyond macronutrients. It also contains essential vitamins and minerals.

These are crucial for the health of fish. Exploring these micronutrients sheds light on the potential benefits for guppies.

Catering to Betta Fish-Specific Proteins:

Proteins are vital for fish growth and development. Understanding the protein content in betta food is essential.

Understanding the compatibility of betta food with guppies is crucial. It aids in making informed decisions about their diet.

Can Guppies Eat Betta Food?

Yes, but with considerations. Guppies can indeed eat betta food, but it requires careful consideration.

Consider the size of the pellets and the nutritional needs of guppies to ensure a balanced diet.

It is safe for other fish like Mollies to consume Betta Flakes.

But, it is best to feed fish of other species a food that is specially made to meet their nutritional demands. Bettas don’t need the same nutrition as other fish.

Moreover, you can feed freshwater Guppies more than just store-bought fish food.

Brine shrimp, bloodworms, daphnia, and blanched veggies like zucchini or peas are a few more alternatives.

It’s critical to make sure the food is safe for the Guppies and suitable for their size.

Guppies have smaller mouths than bettas, highlighting the importance of selecting sized pellets.

Ensure the size is suitable for guppies to prevent potential feeding challenges.

How to Feed Betta Fish and Guppies in a Tank?

Feeding both guppy fish with betta in the same tank can be challenging. This is because they have distinct eating behaviors.

Guppies are greedy eaters, consuming anything they find. But, bettas are slower and more observant eaters.

Although Guppies will consume any kind of flake meal, premium varieties that have both protein and vegetable matter are best.

Moreover, flake food planned for tropical fish regularly contains natural color enhancers that will make your Guppies appear brighter and more colorful.

To feed both species, I consider the following technique:

Separate Feeding Areas:

Place plant-based or meat-based fish food in one part of the tank to attract guppies.

While your guppies are busy eating, find your betta fish. Feed it with a meat-based fish food that you’ve chosen.

Make sure the food is suitable for bettas and meets their nutritional needs. 

This strategy helps ensure both your guppy and betta fish are well-fed in the same tank.

If guppies eat, set up many feeding areas. This ensures a fair share for each species.

Observe their feeding behavior to adjust their diets for harmony.

This feeding strategy usually works well, ensuring both species are satisfied. If guppies tend to consume all the betta food.

Then create more feeding places next time to provide a fair share for both. Distribute food in different spots in the aquarium.

This increases the likelihood of your betta getting some food. There may be instances where bettas attempt to eat guppy plant-based food.

Not to worry, as bettas can tolerate small amounts of plant fish food.

If both species are feeding together, try combining plant-based and meat-based food. 

Bettas will choose their preference, and guppies will get a well-rounded nutritional intake.

This mix ensures each fish gets the nutrients they need for a balanced diet.

Easy Tips for Feeding Guppies Betta Food

Pellet Size Matter:

The right size of betta food pellets matters for feeding. Pellet size should be 25% – 50% of the fish’s mouth.

It is necessary to opt for small and digestible sizes for guppies in a tank.

Ingestible pellets to reduce the risk of choking and ensure optimal consumption. 

Beyond Betta Food: A Balanced Diet for Guppies

1. High-Quality Flakes or Pellets:

Use a good-quality guppy food flake or pellet as a main food. Try to provide a good balance of proteins, fats, and carbohydrates.

2. Live or Frozen Foods:

Add live or frozen foods to their diet. It is good to keep their natural eating habits. Also, give them extra nutrients. Some good options are given below:

  • Brine Shrimp: Rich in protein, a favorite for many aquarium fish.
  • Daphnia: Small crustaceans that are high in fiber and promote digestion.
  • Bloodworms: A protein-rich option that enhances coloration.

3. Vegetable-Based Foods:

Guppies also like eating vegetables. You can add:

Spirulina Flakes: These are rich in essential vitamins and minerals. It enhances their immune system and coloration.

Vegetable-Based Pellets: Certain pellets have spirulina and plant-based ingredients. Blue-green algae is a good source of protein, vitamins, minerals, and antioxidants.

4. Homemade Gel Food:

Blend veggies, fish flakes, and gelatin for guppies’ food. Customize it as you like.

5. Feeding Frequency:

Betta food, whether in pellet or flake form, sometimes can be given to guppies as a treat rather than a regular part of their diet.

While betta food is rich in protein and suitable for the carnivorous nature of bettas, guppies need a more balanced diet.

I suggest offering betta food to guppies once or twice a week in small amounts to avoid overfeeding.

For guppy fry, it’s important to provide finely ground food to cater to their small mouths.

This ensures a well-rounded nutritional intake for the guppies.

Usually, I feed a normal diet to adult guppies as much as they can consume in a minute, once or twice a day.

If you have growing fry, you can feed them three or five times a day.

But you should make sure that each meal is significantly lower in quantity to avoid polluting the water with too much food.

7. Supplements:

Add vitamin or mineral supplements to their diet. Yet, be careful not to over-supplement. It can also lead to health problems.

8. Clean Water:

Maintain good water quality through regular water changes and appropriate filtration.

You should remove toxic plants and uneaten foods regularly from an aquarium.

Because, like Betta fish, Guppies need clean oxygen-rich water, ensure tanks are well aerated and filters are cleaned regularly.

Guppies’ Behavior After Diet Change

Observing guppies’ behavior after diet changes is crucial for ensuring their well-being. I suggest the following indicators should be observed in this regard. 

Feeding Response:

  • A healthy guppy will eagerly swim to the surface or designated feeding area when food is introduced.
  • Vigorous feeding behavior, where guppies actively chase and consume food, indicates a positive response to the diet.

Activity Level:

  • Guppies that exhibit lively and energetic swimming patterns are generally in good health.
  • Sluggish or inactive behavior might indicate that the new diet is not providing sufficient energy or nutrients.


  • A well-balanced diet rich in essential nutrients, such as pigments like carotenoids, contributes to vibrant and bright coloration in guppies.
  • Dull or faded colors may indicate a lack of certain nutrients in the diet.

Fecal Output:

  • Healthy guppies produce regular, well-formed feces. Any sudden change in fecal patterns, such as discoloration or irregular shapes, may indicate digestive issues or an inappropriate diet.

Fin Health:

  • A nutritious diet contributes to the overall health of guppies, including their fins.
  • Strong, undamaged fins are a positive sign, while frayed or torn fins may suggest nutritional deficiencies.

Social Behavior:

  • Guppies are social fish and a harmonious community suggests a healthy environment. 
  • Increased aggression, bullying, or male guppies fighting may result from stress related to a change in diet or inadequate nutrition.

Reproductive Behavior:

  • Balanced nutrition supports reproductive health. Rounded, gravid females and males displaying courtship behavior indicate a positive response to the diet.

Consistency in Behavior:

  • Guppies may exhibit temporary changes in behavior when a new diet is introduced. Allow time for them to adjust before making conclusions about the diet’s impact.

Document Changes:

  • Maintaining a record of feeding schedules, diet changes, and observed behaviors helps in tracking the impact of dietary adjustments over time.
  • If concerns arise, these records are valuable when seeking advice from a veterinarian.

Monitoring the behavior of your guppies after introducing betta food provides valuable insights.

Any adverse reactions or reluctance to eat may signal the need for adjustments in their diet.

Final Thoughts

Keeping guppies with other species, such as bettas, adds a dynamic vibe to your aquarium.

The mix of different fish enhances the aquarium experience. But, caring for these diverse species comes with responsibility.

Always understand the specific dietary needs of each fish. Even common ones can have unique requirements.

Don’t underestimate this crucial aspect. When considering if guppies can eat betta food, the answer is yes, but you need to be attentive.

To keep your fish healthy, you must understand what guppies eat.

Take a closer look at the ingredients in betta food and follow careful feeding practices.

In conclusion, the fact is important to understand the complex details of their dietary needs.

Observe how your fish behave and make changes to their diet. This helps create a thriving and peaceful aquarium.

Dedicate yourself to caring for them. You’ll find keeping guppies and bettas becomes a fulfilling and rewarding journey.
