Fish That Will Eat Guppy Fry

Guppy fry can be eaten by many different types of fish. Common predators that will eat guppy fry are larger species such as Angelfish, Silver Dollars, Oscars, and other Cichlids. These predatory fish are not the only ones that may have a taste for guppy fry though; some smaller species, such as Tetras and Barbs may also feed on them.

Guppies should generally not be kept with any predatory fish as they may become an easy meal for these creatures. It is best to provide plenty of hiding spots in the tank so that the guppy fry can find safety if needed. Additionally, it is important to make sure that all adult fishes are well-fed before introducing them into the same tank with guppies or their young. Guppy fish, with their vibrant colors and graceful fins, are a popular choice among aquarium enthusiasts. Their peaceful nature and ease of care make them an excellent addition to both beginner and experienced hobbyists’ tanks. However, guppy owners often face a common challenge: what to do with the surplus of guppy fry that inevitably result from breeding. In this blog post, we’ll explore various fish species that can be effective guppy fry predators, shedding light on natural behavior, benefits, and considerations for keeping these predators in your aquarium.

Fish That Will Eat Guppy Fry

Fish that will eat guppy fry can be a difficult problem to manage for aquarium owners. While some larger fish, like cichlids and angelfish, may prey on the young guppies if given the opportunity, many other types of fish are happy to supplement their diet with guppy fry. Some good choices include barbs such as Tiger Barbs or Cherry Barbs, as well as Danios and even large Tetras like Black Skirt Tetras.

By choosing these species of fish, you can help ensure your tank is free from hungry predators while still providing plenty of food for your adult guppies and their offspring.

The Guppy Fry Dilemma

Before diving into the world of guppy fry predators, it’s essential to understand why this dilemma exists. Guppies are known for their prolific breeding habits, with females giving birth to live fry instead of laying eggs. Each female guppy can produce dozens of fry during her lifetime, leading to overcrowding in the tank if left unchecked. Without intervention, this overpopulation can result in stressed and unhealthy guppies.

To address this issue, many aquarium enthusiasts seek ways to control the guppy population. One natural and effective method is to introduce guppy fry predators into the tank, allowing for a balance between the adult guppies and their offspring.

Which Fish Eat Guppy Fry?

Many fish species, including larger guppies, are known to feed on their own fry. Certain cichlids, such as the convict and blue ram cichlid, have been reported to eat guppy fry. Other commonly kept aquarium fish that may also prey on guppy fry include angelfish, barbs, gouramis, and some tetras.

It is important to research a potential tankmate’s diet before adding it to an aquascape containing livebearers like guppies—as these fish can quickly become snacks for other carnivorous inhabitants of the tank!

Will My Other Fish Eat Baby Guppies?

In general, other adult fish will not eat baby guppies. Baby guppies are much too small for most other types of fish to be interested in eating them. Suppose the tank is overcrowded with adult guppies. In that case, you may find that some of the larger specimens will try and hunt down smaller ones as a food source, so it is important to make sure that your tank has an adequate amount of space and hiding spots for young fry to hide from potential predators.

Additionally, if there are other species in the same aquarium which have different dietary requirements (such as cichlids or catfish), they may view baby guppies as a snack and attempt to feed on them; however, this can usually be avoided by keeping compatible species together or providing plenty of hiding places for young fry.

Common Guppy Fry Predators

  1. Adult Guppies: Surprisingly, adult guppies themselves can be guppy fry predators. Some female guppies may consume their own fry, especially if they feel threatened or stressed. This behavior is more likely in crowded or suboptimal tank conditions.
  2. Mollies (Poecilia spp.): Mollies are closely related to guppies and share similar care requirements. They are known to be voracious eaters and readily consume guppy fry if given the chance. However, it’s essential to ensure the tank size is adequate, as mollies can become aggressive if overcrowded.
  3. Platies (Xiphophorus spp.): Platies are another guppy-friendly fish species that can help control the guppy fry population. They are generally peaceful and easy to care for, making them suitable tank mates for guppies.
  4. Swordtails (Xiphophorus hellerii): Swordtails are slightly larger than guppies and have a peaceful temperament. They readily consume guppy fry but are not aggressive toward adult guppies.
  5. Gouramis (Trichogaster spp.): Some gourami species, such as the dwarf gourami, can be effective guppy fry predators. However, be cautious when choosing gouramis, as some can be territorial and aggressive.
  6. Betta Fish (Betta splendens): Betta fish, also known as Siamese fighting fish, can consume guppy fry. However, bettas have a reputation for being territorial and may not be compatible with guppies in the long run.
  7. Tetras (Various Species): Certain tetra species, such as neon tetras or black skirt tetras, may eat guppy fry if given the opportunity. Keep in mind that tetras are schooling fish and need to be kept in groups to thrive.
  8. Dwarf Cichlids (Various Species): Some dwarf cichlid species, like Apistogramma, can serve as guppy fry predators. These colorful and fascinating fish add diversity to your aquarium but may require a bit more care and attention.

Will Angelfish Eat Guppy Fry?

Yes, angelfish will eat guppy fry. It is important to note that this behavior depends on a few factors, such as the size of the angelfish and how hungry it is. Generally speaking, if an angelfish has access to other food sources then it may not turn to smaller fish like guppy fry for sustenance.

However, in cases where an angelfish do not have enough food or when its tank mates are much larger than them, they may start hunting for small prey like guppy fry. To prevent this from happening, ensure that you feed your tank inhabitants correctly and provide adequate hiding places for the young fish so they can escape any potential predators.

How Do You Stop Guppies from Eating Fry?

One of the best ways to stop guppies from eating fry is to feed them multiple small meals throughout the day rather than one large meal. This will help keep them satiated and reduce their urge to snack on their smaller tank mates. Additionally, you can try adding floating plants or an extra hiding place in your aquarium so the fry has more places to hide when they feel threatened by the larger fish.

Finally, removing excess food from your tank after feeding time can also help prevent guppies from snacking on any unsuspecting fry who gets too close!

Best Fish to Control Guppy Population

If you have a guppy population that is getting out of control, one of the best fish to introduce in order to help manage it is a larger and more aggressive fish species. Fish like Siamese Fighting Fish or Bristlenose Plecos are two good choices as they can consume excess food while also providing competition for the guppies, thus helping keep them in check. However, when introducing these larger fish into an aquarium with existing guppies, make sure to do so slowly and observe their behavior carefully—you want them to keep the Guppy population under control without posing any danger themselves.

Benefits of Using Guppy Fry Predators

Introducing guppy fry predators into your aquarium can offer several benefits:

  1. Population Control: The most apparent benefit is that these predators help manage the guppy population, preventing overcrowding and reducing the risk of stress-related diseases.
  2. Natural Behavior: Many of the fish listed above exhibit natural predatory behavior, which can be captivating to observe in an aquarium setting. It adds an element of realism to your tank.
  3. Diversity: Keeping a mix of fish species can make your aquarium more visually appealing and interesting. Guppy fry predators come in various colors, sizes, and shapes, adding diversity to your aquatic community.

Best Fish for Fry Control

Fish That Will Eat Guppy Fry

When it comes to controlling fry populations, the best fish for this purpose are carp, grass carp, and fathead minnows. Carp are known as bottom-feeders, meaning they feed on smaller organisms living in the mud at the bottom of ponds or lakes. Grass carp consume aquatic vegetation, while fathead minnows feed mainly on insect larvae and small crustaceans found near shorelines.

All three species can help reduce fry populations by consuming them before maturity.

What Fish Will Eat Guppies?

Guppies are a popular fish for home aquariums, and they make an excellent food source for other fish. Common species that will readily consume guppies include cichlids, goldfish, large minnows, catfish, Siamese fighting fish (Betta splendens), and loaches. Some of these predators should be kept with caution as they may become aggressive toward the guppy in order to protect their territory or even attempt to eat them all!

Will Dwarf Gourami Eat Guppy Fry?

Dwarf Gourami are a peaceful species of fish, and they generally do not eat guppy fry. In fact, they may even help protect the fry from other tank mates by chasing them away if there is any aggression toward the smaller fry. However, if Dwarf Gourami become overly hungry or their food supply is limited, it’s possible that they will start to snack on guppy fry as an additional source of nutrition.

To ensure that this doesn’t happen, it’s important to feed your Dwarf Gourami regularly with a variety of high-quality foods and provide plenty of places for the guppies to hide so they can stay safe from predators in the aquarium.

What Fish Will Eat Platy Fry?

Platy Fry are small, delicate fish that are a great addition to the aquarium. However, be aware that some other types of fish may eat them! Common culprits include cichlids, goldfish, and larger species of tetras.

To ensure the safety of your Platy Fry, it is important to research the tankmates you intend to introduce before adding them in order to avoid potential predators.

Fish That Eat Baby Fish

Many fish species are known to eat baby fish as a diet. This includes predatory fish such as pike, trout, bass, and barracuda that consume smaller prey in order to survive. Baby fish can also be eaten by scavenger species like catfish, carp, and gar that feed on dead or dying organisms in the water.

It is important for predators to target small prey items so they don’t expend too much energy chasing down large meals.

Will Rams Eat Guppy Fry?

Yes, Rams will eat guppy fry. Guppies are small freshwater fish with bright colors and patterns that many people like to keep in aquariums. Unfortunately, they can reproduce very quickly, and their numbers can get out of control if not managed properly.

In addition to being voracious predators of other fish, such as guppies, some species of Rams will also feed on guppy fry when given the opportunity.

Will Tetras Eat Guppy Fry?

Tetras can be an interesting addition to a home aquarium, but it is important to note that they should not be kept with guppy fry. While adult tetras may not actively hunt and eat tiny guppy fry, the smaller size of the fry makes them vulnerable to being eaten by larger fish such as tetras. Therefore, if you want your guppies to survive and thrive in your tank, make sure there are no tetras present when introducing new young fish.


The Fish That Will Eat Guppy Fry blog post has provided a comprehensive guide to understanding which fish can be safely kept with guppies and their fry. As long as the tank is set up properly, with appropriate water parameters and plenty of hiding spots, these species should make excellent companions for guppies. Even if certain species are not suitable for a particular aquarium environment, they may still be suitable in other tanks with enough space to comfortably accommodate them.

Introducing guppy fry predators into your aquarium can be a practical and natural way to manage the guppy population while adding diversity and intrigue to your aquatic community. However, it’s essential to carefully select compatible predator species, provide adequate tank space, and maintain a balanced diet for all your fish. Ultimately, the decision to use guppy fry predators should align with your goals as an aquarium enthusiast. Whether you’re interested in population control, observing natural behaviors, or creating a visually appealing tank, understanding the dynamics of predator-prey relationships can help you achieve a harmonious and thriving aquatic environment for your guppy fish and their tank mates.
It’s important to carefully research any potential companion before introducing it into your tank to ensure that all of your fish thrive together happily and healthily.
