In this article, I’ll delve into this topic, outlining the pros and cons, and explaining why you might want to avoid feeding ants to guppies altogether.

Are Ants Safe for Guppies to Eat?

When it comes to feeding live food to guppies, many aquarists opt for daphnia, brine shrimp, or mosquito larvae, all of which are a natural part of their diet. However, ants are not a usual meal for them, which brings up the question of safety. While guppies are curious and adaptable fish, there are a few reasons why ants might not be the best choice for their diet.

Firstly, the exoskeleton of ants can be difficult for guppies to digest. This could lead to an impaction, negatively affecting the guppy’s health. Guppies have small digestive systems, and the hard exoskeleton of ants can cause obstruction or difficulty passing through their digestive tract.

Secondly, ants are known to be aggressive and able to protect themselves with their powerful mandibles or even by biting. There’s a chance that the ants’ natural defense mechanisms can harm your guppy. While guppies might attempt to take bites out of larger ants, they may not be able to handle the struggle or even injure themselves in the process.

Lastly, ants can carry diseases and parasites. If the ants you are considering feeding to your guppies have been in contact with pesticides or fertilizers, it could lead to toxic consequences for your fish. Moreover, ants can harbor bacterial or fungal infections that could transfer to your guppies, putting their health at risk.

Are Ants Larvae Good for Guppies?

Ant larvae, also known as ant brood, are a fascinating food source. They’re packed with protein and nutrients, which could make them a nutritious treat for guppies. However, several concerns arise when considering them as a viable food option:

  • Digestibility: Like adult ants, ant larvae also have exoskeletons, albeit less developed. These exoskeletons can be challenging for guppies to digest, leading to potential health complications.
  • Safety: Although ant larvae are less aggressive than adult ants, their natural defense mechanisms could still harm your guppies.
  • Disease Transmission: Ant larvae, just like adult ants, can harbor bacteria, fungi, or parasites that may infect your guppies.

Considering these concerns, ant larvae may not be the best option for our little aquatic friends.

Why You Should Not Give Your Guppies Ants

Aside from the safety concerns already mentioned, there are several reasons why ants are not an ideal food option for your guppies.

  • Unnecessary nutritional risks: Guppies can thrive on a well-balanced diet of quality prepared foods such as flakes and pellets, along with occasional treats of live or frozen foods, like daphnia and brine shrimp. These food options are specially formulated to meet their nutritional needs, while ants may not provide a complete and balanced diet.
  • Feeding difficulties: Ants are fast and agile creatures which can pose a challenge to guppies trying to catch and eat them. Moreover, ants can escape from tanks easily, leaving you with escaped ants in your home.
  • Availability: Unless you’re collecting ants from your own backyard, which could be risky due to potential exposure to pesticides or other contaminants, finding a reliable source of ants can be challenging. On the other hand, there are various easy-to-find and nutritionally appropriate alternatives available for guppies that you can purchase from pet stores.
  • Ethical concerns: In some cases, there might be ethical considerations to factor in when considering the use of live food, with some people not feeling comfortable feeding live insects to their pets.

Overall, although it might be tempting to try feeding ants to your guppies, it’s clear that the risks associated with this practice outweigh any potential benefits.

It’s always better to stick to tried-and-tested nutritional approaches, such as a good quality flake food and occasional live or frozen treats. This will ensure the health and well-being of your guppies while removing any unnecessary risks.

What Wild Insects Can Guppies Eat?

While ants may not be suitable for guppies, there are other wild insects that can provide a valuable source of nutrients to your guppies as occasional treats. Some of these include:

  • Mosquito larvae: These are a natural part of guppies’ wild diet and are packed with nutrients that can boost their growth and health. They’re readily available in some pet stores or can be collected from standing water outside.
  • Daphnia: Also known as water fleas, these small aquatic crustaceans are an excellent live food choice for guppies. Daphnia can be found in outdoor ponds or purchased from pet stores.
  • Brine shrimp: Though not technically an insect, brine shrimp are another popular live food option for guppies. They are a nutritional powerhouse, packed with essential amino acids and fatty acids. You can either buy brine shrimp eggs and hatch them at home or purchase live or frozen brine shrimp from a pet store.
  • Fruit flies: These tiny insects are often used as live food for smaller fish like guppies. You can buy cultures of fruit flies from pet stores or even breed them at home.
  • Micro worms: These are tiny nematodes that are another nutritious live food option for guppies. They can be easily cultured at home or purchased from a pet store.

When opting for wild insects as food for your guppies, always ensure that they have not been exposed to pollutants, pesticides, or other harmful chemicals. Additionally, it’s essential to remember that these should be given only as treats and not as the primary source of nutrition.

A balanced diet consisting of commercial flakes, pellets, and occasional live or frozen food options will keep your guppies happy, healthy, and thriving.

Ant Alternatives for Guppies as Live Food

As we’ve established, ants may not be the best choice for guppies due to various safety concerns and nutritional limitations. However, there are numerous alternative live food options that will provide your guppies with the nutrition they need and offer more suitable feeding experiences. Some potential ant alternatives include:

  • Bloodworms: These are the larvae of midge flies, and they’re a nutritious live food option for guppies. Bloodworms are rich in protein and can be bought either live, frozen, or freeze-dried from pet stores.
  • Moina: Moina, often referred to as “mini daphnia,” is a smaller relative of daphnia, which makes it an excellent live food choice for guppies because of their smaller size. They can be found in ponds or bought from aquarium suppliers.
  • Infusoria: This term refers to microscopic aquatic organisms such as protozoans, algae, and bacteria that thrive in nutrient-rich water. Infusoria is especially suitable for guppy fry (babies) as their small size might make it difficult for them to consume larger food items. You can purchase Infusoria cultures from pet stores or cultivate your own at home.
  • Vinegar eels: These are tiny nematodes that live in acidic environments, such as vinegar. They provide an excellent live food option for guppy fry, and their culture is relatively easy to maintain at home.
  • Copepods: These small crustaceans are yet another nutritious live food choice for guppies. They can be found in outdoor ponds or purchased from pet stores.

When introducing any live food to your guppies’ diet, it’s crucial to ensure that they are sourced from clean and uncontaminated environments. Doing so will reduce the risk of introducing diseases or harmful substances to your aquarium.

Furthermore, always remember that while live food can offer valuable nutrients, it should be given as an occasional treat rather than a staple in your guppies’ diet.


In conclusion, while the idea of feeding ants to guppies might seem intriguing, the potential risks and drawbacks significantly outweigh any perceived benefits. Guppies can thrive on a balanced diet of high-quality commercial food and occasional live or frozen food options, such as mosquito larvae, daphnia, and brine shrimp.

Introducing ants to their diet can pose various safety concerns and nutritional imbalances, making it an unsuitable choice for these small, adaptable fish. Instead, consider the numerous alternative live food options mentioned above that can safely provide essential nutrients to keep your guppies happy and healthy.

Always source live food from clean and uncontaminated environments and remember to provide these treats as a supplement to their primary diet.
