Feeding Guppies: What You Need to Know

Are you a proud owner of guppies or planning to keep them as pets? One of the essential aspects of keeping these colorful tropical fish healthy and happy is providing them with a well-balanced diet.

In this article, we will delve into what guppies eat, how often should they eat, and factors that impact their feeding habits. What Do Guppies Eat?

The first question that comes to mind when feeding guppies is what to feed them. The good news is that guppies are not too fussy when it comes to their food.

A variety of food options are available, including fish flakes, veggie pellets, freeze-dried foods, vegetables, meat, and live food. Commercial fish food is a convenient option and can be found in most pet stores.

These fish flakes or pellets are designed to meet the nutritional requirements of guppies. However, it is essential to know that not all commercial fish food is created equal.

Look for reputable brands that use high-quality ingredients and include vitamins and minerals essential for the fish’s well-being. If you prefer homemade guppy food, you can try making veggie pellets using ingredients like cooked peas, carrots, or spinach puree, mixed with gelatin.

Another option is to make guppy treats using freeze-dried foods like brine shrimp, blood worms, or mosquito larvae. Remember to check the nutritional content of homemade food and supplement it with commercial fish food if needed.

Besides, guppies enjoy live food like soft algae, insect larvae, blood worms, vinegar eels, and tubifex worms. You can opt to produce your own live food or buy them from pet stores.

However, it is crucial to maintain proper hygiene when feeding live food to avoid introducing harmful parasites or bacteria into your tank. What About Guppy Fry?

Guppy fry are baby guppies that require special attention when it comes to feeding. Their tiny mouths can only take in small quantities of food.

As such, guppy fry should be fed with baby brine shrimp, guppy flakes, daphnia, or micro worms. It is crucial to offer guppy fry small portions of food at a time, ensuring that they consume it all before adding more.

Overfeeding may cause digestive problems and lead to swim bladder disease, which can be fatal.

Types of Guppy Food

Variety is the spice of life, and this is also true when it comes to feeding guppies. Offering diverse types of food ensures that guppies receive a balanced diet and do not suffer from nutrient deficiencies.

Here are some types of guppy food you can include in their diet:

– Commercial fish food: as mentioned earlier, commercial fish food is a convenient and easy way of feeding guppies. – Homemade guppy food: you can experiment with homemade guppy food by making veggie pellets or guppy treats.

– Freeze-dried foods: treats like brine shrimp, blood worms, or mosquito larvae can be found in most pet stores and are excellent sources of protein. – Live food: soft algae, insect larvae, blood worms, vinegar eels, and tubifex worms should be fed with care, but they offer a variety of nutrients and are enjoyable for guppies.

How Often Should Guppies Eat? Adult guppies should be fed once or twice daily, depending on their age and activity level.

A common guideline is to feed them five to eight times a day with small portions. Overfeeding can lead to constipation, bloating, and swim bladder disease, while underfeeding can cause malnourishment.

Strike a balance, and monitor your guppies’ weight and overall health regularly. On the other hand, guppy fry need to be fed several times a day, with small portions of food.

They have a fast metabolism and require adequate nutrition to grow healthy and strong.

Factors Affecting Guppy Feeding

Several factors can impact the feeding habits of guppies, including the tank temperature, cleanliness, and lighting.

Tank Temperature

Guppies are tropical fish and thrive in temperatures between 75 to 80 degrees Fahrenheit. Ensure that the tank water is at a stable temperature to prevent fluctuations that may affect their appetite.

During colder months, use a heater to maintain the desired temperature.

Tank Cleanliness

Clean, clear waters are crucial for guppy health and well-being. A dirty tank can lead to bacterial growth and affect the fish’s feeding habits.

Install a good filter and perform partial water changes weekly to maintain a clean environment.


Guppies need a well-lit environment with a proper balance between light and darkness. They are prone to spine problems if kept in the dark for too long.

Provide a dark period for rest and prevent over-exposure to light, which may cause stress and affect their appetite.


In conclusion, feeding guppies is a simple task that requires attention to detail and the right resources. Offer a variety of food options, monitor feeding frequency, and keep the tank conditions optimal for your fish.

By following a few basic guidelines, you can ensure that your guppies remain healthy, active, and happy pets for years to come. In the previous section, we discussed the basics of feeding guppies.

In this section, we will dive deeper into why proper guppy feeding is crucial, as well as explore some miscellaneous feeding information.

Importance of Proper Guppy Feeding

Nutrients and Minerals

One of the primary reasons for proper feeding is to ensure that guppies receive all the nutrients and minerals they need to maintain their colorful nature and resistance to infections. Guppies require high amounts of proteins and macronutrients, found in commercial fish food, live food, and freeze-dried foods like brine shrimp or blood worms.

In addition, vitamin-rich vegetables like peas, spinach, or carrots are essential in providing the necessary vitamins for the fish. Feeding guppies a well-balanced diet not only enhances their vibrant colors and shiny scales but also boosts their immune system against common diseases and infections.


Another crucial factor affected by guppy feeding is their lifespan. Guppies can live for up to two years, with proper care, which includes the right feeding habits.

A study by the University of California, Riverside, found that wild guppies’ diet in moving waters consisted of high amounts of algae and small invertebrates. As such, guppies can be considered picky eaters that need specific nutrients to thrive.

It is essential to mimic their natural diet as closely as possible while providing a variety of food options. By feeding guppies a well-balanced diet, you can help prolong their lifespan and enjoy their beauty for years to come.

How to Tell When Guppies are Hungry

One of the common questions most guppy owners have is, “How do I know when my guppies are hungry?” Guppies can exhibit different behaviors when they are hungry. Swimming patterns: When guppies are hungry, they may start to swim more actively, darting around the tank, and showing general fidgetiness.

Inactivity: Conversely, guppies may also become more inactive, hovering near the bottom or hiding out in one spot. Aggression: When hungry, guppies may also become more aggressive towards other fish, circling them and nipping at their fins.

Digging into substrate: Guppies may also dig and search for leftover food particles in the substrate when they are hungry. Observing your guppies’ behavior and feeding frequency can help you determine when to feed them and prevent over or underfeeding.

Miscellaneous Guppy Feeding Information

Length of Time Guppies can go Without Food

Guppies are hardy and resilient pets that can go without food for up to two weeks. However, it is not advisable to let your guppies starve for that long.

Goldfish flakes can be an alternative temporary food source that can sustain guppies in case of an emergency.

Guppies Eating Goldfish and Algae

Guppies are omnivorous and can eat a variety of things, including specialized foods like goldfish flakes. However, care should be taken when feeding goldfish flakes to guppies as they contain high-fat contents and lack essential minerals necessary for guppy health.

Guppies also enjoy eating algae, but not all types of algae are safe for them. Algae can be found growing on decaying plants or on the tank walls and can be a source of natural food for guppies.

However, some types of algae may not be healthy for them and can lead to digestive problems if consumed in large quantities.

Human Foods That Guppies Eat

Guppies are opportunistic feeders and can eat a variety of human foods. However, not all human foods are healthy or safe for them.

Avoid feeding your guppies foods that contain bread, yeast, sugar, artificial coloring, or corn syrup. These foods lack essential nutrients, and some may even be harmful to your guppies.


In conclusion, feeding guppies a well-balanced diet, monitoring their feeding frequency, and observing their behavior is essential for their health, lifespan, and overall well-being. It is crucial to understand their natural diet, provide a mix of commercial fish food, homemade food, and live food, and maintain optimal tank conditions for healthy growth.

With proper feeding and care, your guppies can be a joy to watch and a valuable addition to your home aquarium. Proper feeding habits are crucial for maintaining the health and well-being of guppies.

By offering a variety of food options, monitoring feeding frequency, and maintaining optimal tank conditions, guppies can thrive and live long, vibrant lives. Observing their behavior and offering a well-balanced diet consisting of commercial fish food, homemade food, and live food can provide the necessary nutrients and minerals required to maintain their colorful nature and resistance to infections.

A conclusion to take away is that it is important to ensure that guppies receive proper nutrition through their diet, which ultimately results in a happy and healthy pet that brings joy to your home aquarium.
