Do Plecos Eat Shrimp? Uncovering the Truth

Plecos, also known as plecostomus or suckerfish, are popular freshwater aquarium fish known for their algae-eating abilities. Many aquarium enthusiasts wonder whether plecos eat shrimp, as both species are commonly kept together in aquariums. In this article, we will explore the truth behind this question and provide you with valuable insights into the feeding habits of plecos and their compatibility with shrimp.

Understanding Plecos’ Diet

Plecos are primarily herbivorous fish that feed on algae and plant matter. They have a specialized mouth structure with suction-like lips, which allows them to scrape algae off surfaces. While algae make up a significant portion of their diet, plecos also consume other plant-based foods such as vegetables and sinking pellets.

However, it’s important to note that plecos are opportunistic feeders and may also consume small invertebrates or animal-based foods if available. This includes small crustaceans like shrimp, as well as insects and worms. Their diet can vary depending on the availability of food in their environment.

Do Plecos Eat Shrimp?

The answer to whether plecos eat shrimp is not a straightforward one. While plecos have been observed consuming shrimp in certain situations, it is not their primary food source. In most cases, plecos will not actively hunt or prey on shrimp in a well-fed aquarium environment. Their main focus remains on algae and plant matter.

However, it’s crucial to consider the size and temperament of both the plecos and the shrimp. Larger pleco species, such as the common pleco (Hypostomus plecostomus), may be more likely to consume small shrimp due to their size and ability to swallow larger prey. On the other hand, smaller pleco species and juvenile plecos are less likely to eat shrimp.

Factors to Consider

Several factors can influence whether plecos will eat shrimp in an aquarium setting:

  1. Size Difference: Plecos that are significantly larger than the shrimp may pose a greater risk of predation.
  2. Hiding Places: Providing ample hiding places for shrimp, such as plants, caves, or driftwood, can help them avoid being targeted by plecos.
  3. Feeding Habits: Ensuring that plecos are well-fed with a balanced diet of algae and plant-based foods can reduce their inclination to seek out shrimp as a food source.
  4. Compatibility: Some species of shrimp, such as cherry shrimp or amano shrimp, are known to coexist peacefully with plecos in aquariums without any issues.

Tips for Keeping Plecos and Shrimp Together

If you want to keep plecos and shrimp together in your aquarium, follow these tips to promote a harmonious and safe environment:

1. Provide Sufficient Hiding Places

As mentioned earlier, offering plenty of hiding spots for shrimp will allow them to feel secure and avoid potential predation by plecos. Live plants, caves, and driftwood are excellent options to create hiding places in your aquarium.

2. Feed a Balanced Diet

Ensure that your plecos receive a varied and balanced diet that includes algae, vegetables, and sinking pellets. By providing them with an abundance of their preferred foods, you reduce the chances of them seeking out shrimp as an alternative food source.

3. Choose Compatible Shrimp Species

When selecting shrimp for your aquarium, opt for species that are known to coexist peacefully with plecos. Cherry shrimp, amano shrimp, and ghost shrimp are popular choices that have been successfully kept with plecos.

4. Monitor Behavior

Regularly observe the interactions between plecos and shrimp in your aquarium. If you notice any signs of aggression or predation, such as the plecos actively chasing or nipping at the shrimp, it may be necessary to separate them to ensure the safety of the shrimp.


While it is possible for plecos to eat shrimp in certain circumstances, it is not a common occurrence in well-maintained aquariums. By providing appropriate hiding places, a balanced diet, and compatible shrimp species, you can create an environment where plecos and shrimp can coexist peacefully. Remember to monitor their behavior regularly and make adjustments as necessary to ensure the well-being of both species in your aquarium.

Frequently Asked Questions

Can Plecos Eat Shrimp?

Yes, plecos can eat shrimp. Plecos, also known as plecostomus or suckerfish, are omnivorous fish that have a diverse diet. While their primary diet consists of algae and other plant matter, they are known to be opportunistic feeders and will consume small invertebrates such as shrimp if given the chance. However, it’s important to note that not all plecos will eat shrimp, and their dietary preferences can vary depending on the species and individual fish.

If you want to offer shrimp as part of your plecos’ diet, it’s best to provide them with live or frozen shrimp that are suitable for aquarium fish consumption. You can find commercially available shrimp varieties that are specifically designed for fish like plecos. It’s also important to ensure that the shrimp you offer are of an appropriate size for your plecos to consume without any issues.

Do Plecos Prefer Shrimp Over Other Foods?

Plecos have a wide-ranging diet and are not solely dependent on shrimp for nutrition. While they may consume shrimp if given the opportunity, they also rely on a variety of other food sources to meet their dietary needs. As mentioned earlier, plecos are primarily herbivorous and feed on algae and other plant matter. This forms a significant part of their diet and should be the main focus when it comes to providing them with nutrition.

Offering a diverse diet that includes a mix of plant-based foods, such as algae wafers, vegetables, and fruits, along with occasional protein-rich foods like shrimp, can help ensure that your plecos receive a balanced diet. It’s important to provide them with a variety of foods to mimic their natural feeding habits and promote their overall health and well-being.

Are Shrimp Safe for Plecos to Eat?

Shrimp can be safe for plecos to eat if they are of an appropriate size and quality. It’s essential to choose shrimp that are specifically meant for aquarium fish consumption and free from any harmful chemicals or additives. Live or frozen shrimp that are sold as fish food are generally safe to feed to plecos.

However, it’s important to monitor your plecos’ feeding behavior and ensure that they are able to consume the shrimp without any issues. Shrimp that are too large can pose a choking hazard for plecos, while shrimp that are spoiled or contaminated can lead to health problems. Always observe your plecos during feeding and remove any uneaten shrimp to maintain water quality in the aquarium.

What Other Foods Can I Feed My Plecos Besides Shrimp?

In addition to shrimp, there are several other foods that you can feed your plecos to ensure they receive a balanced diet. As mentioned earlier, plecos are primarily herbivorous and rely on algae and other plant matter for nutrition. You can provide them with specially formulated pleco pellets or wafers that are rich in plant-based ingredients.

Additionally, you can offer your plecos a variety of vegetables such as zucchini, cucumber, and spinach. These can be blanched or cooked before feeding to make them more easily digestible. Fruits like melons and apples can also be given as occasional treats. It’s important to vary their diet and offer a mix of foods to keep them healthy and happy.

How Often Should I Feed Shrimp to My Plecos?

Feeding shrimp to your plecos should be done in moderation. While shrimp can be a nutritious addition to their diet, it should not be the sole focus. Plecos should be primarily fed a diet of plant-based foods such as algae wafers and vegetables. Shrimp can be offered as a treat or occasional protein source.

A good rule of thumb is to feed shrimp to your plecos once or twice a week, depending on their individual needs and preferences. It’s important to monitor their feeding behavior and adjust the amount of shrimp accordingly. Overfeeding shrimp or any other food can lead to health problems for your plecos and negatively impact the water quality in the aquarium.
