What Fish Eat Guppies?

Guppies are small, colorful fish that are popular in aquariums. However, they are also preyed upon by a variety of animals in the wild. Some of the most common fish will eat guppies include:

  • Large fish: Any large, aggressive fish capable of eating guppies will consider them a potential meal. This includes the Oscars, cichlids, red-tiger sharks, leopard bush fish, barbs, and Gouramis.
  • Amphibians: Frogs and turtles are both natural predators of guppies. They will often ambush guppies near the surface of the water.
  • Reptiles: Snakes and lizards will also eat adult guppies. They will typically prey on guppies swimming near the water’s bottom.
  • Birds: Some birds, such as herons and kingfishers, will eat guppies. They often spot guppies from above and swoop down to catch them.
  • Invertebrates: Some invertebrates, such as crayfish and shrimp, will also eat guppies. They will typically prey on guppy babies or small, weak guppies.

In addition to these predators, guppies are also vulnerable to being eaten by other fish in their aquarium. This might happen if the tank is overcrowded or the fish must be compatible. For example, betta fish are known to be aggressive and would eat other fish in their tank.

If you are keeping guppies in an aquarium, choosing compatible tank mates is crucial and ensuring the tank is well-spent. This will help to reduce the risk of your guppies being eaten.

Top 7 Predatory Fish Eat the Guppy Fry

1. Gourami

Gouramis are beautiful tropical fish known for their vibrant colors and unique personalities. However, they tend to become territorial, especially during guppy breeding times. This territorial behavior might lead them to consider the guppies as intruders, causing potential harm.

2. Cichlid

Cichlids are known for their intelligence and intricate social structures. While some species are more peaceful, others can be highly aggressive. Aggressive cichlids might perceive guppies as competitors or threats and may attack them.

3. Angelfish

Angelfish have striking, angelic appearances that captivate aquarists. Despite their serene appearance, they can be predatory and might prey on smaller fish like guppies, especially if they fit in their mouths.

4. Dwarf Pufferfish

Dwarf pufferfish are fascinating creatures with quirky behaviors, but they have a taste for live food, including small fish and invertebrates. Guppies, unfortunately, fall into their menu.

5. Bettas

Bettas, also famous as Siamese fighting fish, are well-known for their beauty and aggressiveness. They are solitary fish and should not be kept with guppies, as they might perceive them as rivals and attack them.

6. Oscars

Oscars are large and powerful fish that require sizeable aquariums. Their size and predatory nature make them unsuitable tank mates for guppies, as this carnivorous fish might see them as a delectable snack.

7. Clown Knife Fish

The clown knife fish is an impressive species often sought after by experienced aquarists. However, they are naturally predatory and will not hesitate to eat smaller fish like guppies.

Fish That Eat Guppy Fry


Swordtails are generally peaceful fish but may view baby guppies as easy prey. While adult swordtails can coexist with guppies, avoiding keeping their fry together is best.

Blue Acara

Blue Acara fish are known to be good parents and fiercely protect their offspring. Unfortunately, they may see guppy fry as a potential food source.

Aggressive and Territorial Fish


While platies are not significant threats to adult fish, they can be territorial and sometimes nip at guppy fins, causing stress and potential harm.

Male Guppies

Believe it or not, male guppies can be aggressive toward other fish, particularly if they feel their territory is being invaded.

Best Practices for Guppy Care

To ensure the well-being of your guppies, it’s essential to consider the following tips:

  • Population Control: Be mindful of your guppy population to prevent overcrowding, which can increase aggression and territorial behavior in the tank.
  • Separate Males and Females: If you have both male and female guppies, consider separating them to avoid overbreeding and potential aggression.
  • Provide Hiding Spots: Create plenty of hiding spots in the aquarium using plants, rocks, or decorations to give guppies a haven.
  • Live Food Alternatives: If you want a varied diet, consider providing live food alternatives like mosquito larvae instead of small guppies.
  • Choose Tank Mates Wisely: Before introducing new fish to the tank, research their compatibility with guppies and their temperament.

What Fish Don’t Eat Guppies?

Many species of fish can coexist peacefully with guppies without harming them. Some examples of fish that don’t eat guppies include neon tetras, platies, swordtails, mollies, and cherry barbs.

It is essential to research the temperament and compatibility of any fish species before introducing them to an aquarium with guppies to ensure a harmonious and safe environment for all the fish.

How to Avoid Overpopulation in Guppy Tanks?

To avoid overpopulation in a guppy tank, it is crucial to control guppies’ breeding. Here are some tips:

  • Separate males and females: One of the most effective ways to prevent overpopulation is to separate male and female guppies. This can be done by keeping them in separate tanks or by using a divider in the tank. This will prevent them from breeding and producing more offspring.
  • Limit the number of females: If you keep both males and females in the same tank, limiting the number of females is vital to prevent overpopulation. A good rule of thumb is to have one male for every two or three females.
  • Remove pregnant females: Female guppies can produce dozens of offspring every few weeks. To prevent overpopulation, it is essential to remove pregnant females from the tank and place them in a separate tank until they give birth.
  • Control feeding: Overfeeding can lead to faster growth and earlier maturity in guppies, leading to increased breeding. Feeding guppies a balanced diet in the right amounts is important to avoid overfeeding.

By following these tips, you can prevent overpopulation in your guppy tank and ensure a healthy and happy environment for your fish.

What to do With Excess Guppy Fry?

If you have excess guppy fry, there are several options for what to do with them:

1. Sell or give away the fry: Guppies are a popular fish species, and other aquarium enthusiasts may be interested in buying or taking your excess fry. You can post in online forums or social media groups dedicated to aquariums to find interested buyers or adopters.

2. Trade the fry in with a pet store: Many pet stores will accept live fish as trade-ins or for store credit. Check your local pet store to see if they will take your excess guppy fry.

3. Keep the guppy babies in a separate tank: If you have the space and resources, keep the excess guppy fry in an independent tank and raise them until they are mature enough to sell or give away.

4. Release the fry into the wild: This is not suggested, as it can cause environmental problems if the guppy fry is not native to the area. Releasing non-native fish species into the wild is illegal in some areas.

It is important to remember that guppies are prolific breeders, and it is important to plan what to do with excess fry to prevent overpopulation in your tank.

What Fish Eat Guppy Fry?

Many fish species will happily eat baby guppies, a tasty and easy-to-catch snack, if given the opportunity. Guppy fry are small and vulnerable, making them attractive prey for many larger fish. 

Some common aquarium fish that may eat guppy fry include:

  1. Adult Guppies: Adult guppies are known to eat their own fry, especially if there is a scarcity of hiding spots or food in the aquarium.
  2. Angelfish: Angelfish are known to eat smaller fish, and guppy fry is no exception.
  3. Tetras: Certain tetra species, like neon tetras, can consume guppy fry.
  4. Swordtails: Swordtail fish may prey on guppy fry, especially if kept in the same aquarium.
  5. Mollies: Mollies can eat guppy fry, mainly when the baby guppies are small and easy to capture.
  6. Gouramis: Some gourami species may see guppy fry as food, mainly if they are small enough.

Dense vegetation, floating plants, or separate breeding tanks are often used to protect the fry from potential predators until they grow more extensive and independent.

What Fish Eat Guppy Tails?

In an aquarium, it is not uncommon to witness an exciting display of interaction among different fish species. One such instance is when fish eat guppy tails.

Guppy Tail Split

Male guppies, known for their vibrant colors and long tail, often fall victim to the nipping behavior of other fish in the tank. One common culprit is the tetra, a small, agile fish that can easily sneak up on the guppies.

Female guppies, on the other hand, are usually spared from this tail-nipping behavior. While it may seem distressing, it is a natural behavior for certain fish to exhibit. Therefore, keeping guppies with other species is essential to ensure compatibility and adequate space to prevent unnecessary fin damage.

What Fish Don’t Eat Guppies?

Several fish species may not eat guppies, but this might vary depending on factors such as the guppy’s size and temperament of the other fish in the aquarium and the availability of other food sources.

Here are some fish species that are generally considered to be compatible with guppies in a community tank:

  • Mollies
  • Cardinal tetras
  • Glassfish
  • Plecos
  • Rasboras
  • White Cloud Mountain Minnows
  • Cory catfish
  • Kuhli loaches
  • Platies
  • Swordtails

These fish are peaceful and non-aggressive and will not bother your guppies. They are also all relatively small, so they are not a threat to larger guppies.

Some other fish that can be kept with guppies include:

  • Neon tetras
  • Ember tetras
  • Rummynose tetras
  • Rosy tetras
  • Penguin tetras
  • Zebra danios
  • White skirt tetras
  • Harlequin rasboras
  • Ember rasboras

These fish are all small and peaceful, making good companions for guppies. However, it is essential to note that some fish, such as neon tetras and ember tetras, may eat guppy fry. If you plan to breed guppies, you must provide plenty of hideouts for the guppy fry to avoid being eaten.

It is also important to avoid keeping guppies with bigger fish species, more aggressive fish, such as cichlids, goldfish, or bettas. These fish may see guppies as prey and will not hesitate to eat them.

When choosing tank mates for your guppies, it is essential to consider the size, temperament, and dietary guppies needs of the fish. You can create a peaceful community tank by choosing compatible fish.

How to Choose Compatible Tank Mates for Your Guppies?

Here are some tips on how to choose the best fish tank mates for your guppies so you won’t have to worry:

  • Consider the size of the fish. Guppies are small fish, so you’ll want to choose similarly sized tank mates. Larger fish may see guppies as prey and could injure or even kill them.
  • Think about the temperament of the fish. Guppies are peaceful fish, so you’ll want to choose tank mates that are also peaceful. Aggressive fish, such as cichlids, could bully or even kill guppies.
  • Take into account the water conditions. Guppies are adaptable fish but do best in water with a pH of 7.0-7.8 and a temperature of 72-78 degrees Fahrenheit. Make sure that your tank mates can also thrive in these water conditions.
  • Consider the diet of the fish. Guppies are omnivores and eat various foods, including flakes, live food, and plants. Make sure that any tank mates you choose have similar dietary needs.
  • Think about the space requirements of the fish. Guppies don’t need much space, but they need enough room to swim and explore. Ensure your tank is big enough for all the fish you plan to keep.

These fish are all peaceful and non-aggressive, and they will make good companions for your guppies. They also have similar water requirements and dietary needs to thrive in the same tank.

If you are looking for tank mates to help control algae in your aquarium, consider adding some snails or shrimp. These invertebrates are not only peaceful and non-aggressive, but they can also help to keep your tank clean.

No matter which tank mates you choose, it is essential to do your research to ensure they are compatible with guppies. Following these tips can create a peaceful and thriving community tank.
