In the multifaceted world of freshwater aquariums, the question “will guppies eat shrimp?” often arises, highlighting the complex dynamics that can unfold in the microcosm of a well-maintained tank. Guppies, renowned for their vibrant colors and peaceful demeanor, are a favored choice among aquarium enthusiasts. Meanwhile, freshwater shrimp, such as the striking cherry shrimp and the industrious amano shrimp, are gaining popularity for their unique appearance and efficient algae-eating habits. The intrigue lies in whether these two diverse aquatic species can coexist harmoniously or if indeed, the question, “will guppies eat shrimp?” presents a potential dilemma for aquarium keepers. In this exploration, we delve into the compatibility and considerations of keeping guppies and shrimp together in the same aquatic environment.

About Guppies and Shrimp

Guppies and shrimp are both popular choices for freshwater aquariums, each bringing their unique charm and characteristics to the aquatic environment. When properly cared for, they can coexist in the same tank, creating a beautiful and dynamic underwater ecosystem. Here’s a closer look at guppies and shrimp in freshwater aquariums:

Guppies (Poecilia reticulata)

Guppies are one of the most beloved and widely kept aquarium fish species. They are known for their vibrant colors, distinctive tails, and active behavior. Here are some key points to consider when keeping guppies in a freshwater aquarium:

  • Variety of Colors: Guppies come in a wide range of colors and patterns, making them highly attractive and sought after by aquarium enthusiasts. Selective breeding has led to the development of various strains, each with its own unique appearance.
  • Livebearers: Guppies are livebearers, meaning they give birth to live fry instead of laying eggs. They reproduce readily in captivity, which can result in a growing population if not managed.
  • Hardy and Easy to Care For: Guppies are hardy and adaptable, making them an excellent choice for beginners. They can thrive in a variety of water conditions and tolerate a wide range of temperatures.
  • Community Fish: Guppies are generally peaceful and can coexist with other peaceful community fish. They are sociable and enjoy swimming in groups.
  • Feeding: Guppies are omnivorous and readily accept a variety of foods, including flake or pellet food, live or frozen foods, and even vegetable matter.

Shrimp (e.g., Cherry Shrimp, Amano Shrimp)

Freshwater shrimp are becoming increasingly popular in the aquarium hobby due to their unique appearance and behavior. Cherry shrimp and Amano shrimp are commonly kept in aquariums. Here are some key points about keeping shrimp in freshwater tanks:

  • Varied Species: There are many species of freshwater shrimp available for aquariums, each with its own unique coloration and characteristics. Cherry shrimp, for example, are bright red and small, while Amano shrimp are larger and transparent with distinctive spots.
  • Algae Eaters: Shrimp are excellent scavengers and will help keep your tank clean by consuming algae, detritus, and uneaten food. They are valuable additions to planted tanks, as they graze on algae without damaging plants.
  • Peaceful and Non-Aggressive: Shrimp are peaceful creatures and rarely display aggressive behavior. They can coexist with most fish species that won’t consider them prey.
  • Reproduction: Shrimp reproduce by laying eggs, which hatch into miniature versions of the adults. It’s essential to provide ample hiding places and vegetation for the young shrimp to survive, as they can be preyed upon by other tank inhabitants.
  • Specialized Diets: While shrimp primarily feed on algae and detritus, it’s a good idea to supplement their diet with specialized shrimp pellets or algae wafers.

Will Guppies Eat Shrimp?

So, will guppies eat shrimp in your aquarium? Guppies are generally considered peaceful, small, and non-aggressive fish. They are typically not aggressive towards other fish or creatures, but their behavior can vary based on factors like tank size, individual temperament, and available food sources. In some cases, guppies may attempt to eat small shrimp, particularly baby or newborn shrimp.

Adult guppies may not pose a significant threat to larger shrimp, but if you have very small or juvenile shrimp in the same tank as guppies, there is a risk that the guppies could prey on them. It’s essential to consider the size and life stage of the shrimp and guppies, as well as the overall size of your aquarium, to assess the compatibility of keeping them together.

If you want to keep both guppies and shrimp in the same tank, providing ample hiding places and vegetation for the shrimp can help reduce the chances of guppies preying on them. Additionally, ensure that your shrimp are adequately fed to reduce the likelihood of guppies seeing them as a potential food source.

Aquarium Setup

Setting up a tank to accommodate both guppies and shrimp requires careful planning to ensure the well-being of both species. Here are some steps and considerations for creating a suitable environment for both guppies and shrimp:

  • Tank Size: The size of your tank will depend on the number of guppies and shrimp you plan to keep. A 10-gallon (about 38 liters) tank is a good starting point, but larger tanks provide more stability and space for both species.
  • Substrate: Use a fine substrate like sand or small gravel, as it allows shrimp to forage and sift through the substrate for food without injuring their delicate appendages.
  • Filtration: Guppies and shrimp both benefit from a gentle filtration system. Using a sponge filter or a canister filter with a sponge pre-filter will help prevent baby shrimp and small guppy fry from being sucked into the filter.
  • Plants: Live plants, such as Java moss, Java fern, and Anubias, provide hiding spots and grazing areas for shrimp. Guppies also enjoy swimming through dense vegetation. Ensure the plants are well-established and provide hiding spaces.
  • Decorations: Use driftwood, rocks, and other aquarium decorations to create caves and hiding spots for shrimp. Guppies appreciate open swimming spaces, so avoid cluttering the tank with decorations.
  • Water Parameters: Keep the water temperature around 72-78°F (22-26°C), which is suitable for both guppies and many freshwater shrimp species. Maintain a neutral to slightly alkaline pH level, around 7.0-7.8.
  • Feeding: Guppies are omnivorous and will eat flake or pellet food. Supplement their diet with live or frozen foods for optimal health. Shrimp primarily feed on algae and detritus, so make sure there is sufficient natural food in the tank. You can also provide specialized shrimp pellets or algae wafers.
  • Breeding: Guppies are prolific breeders, and if you want to keep both species together, be prepared for the guppy population to grow quickly. Shrimp also reproduce, but their offspring are more vulnerable to predation.
  • Water Quality: Maintain good water quality by performing regular water changes and monitoring ammonia, nitrite, and nitrate levels. Clean the substrate and ensure the filter is working properly.

Remember that different shrimp species have varying care requirements, so research the specific shrimp species you plan to keep in your tank. Regular observation and attention to the needs of both guppies and shrimp will help you maintain a successful and harmonious aquatic community.


In conclusion, the question “Will guppies eat shrimp?” is one that underscores the delicate balance that can exist in the world of freshwater aquariums. While guppies are typically peaceful and may not pose a significant threat to adult shrimp, there remains a risk, especially to small or juvenile shrimp. The compatibility of guppies and shrimp in the same tank depends on factors such as tank size, individual temperament, and the availability of alternative food sources. Proper planning, careful observation, and providing hiding places for the shrimp can help mitigate the risk and promote a harmonious coexistence. In summary, yes, guppies can potentially eat shrimp, but with the right precautions and maintenance, it’s possible to create a thriving aquatic community that includes both of these captivating freshwater species.
