Plecos are one of the most popular fish species for hobbyists. They are easy to care for and known for their ability to clean up algae in aquariums. However, there has been a long-standing question on whether plecos eat other fish in their tanks.
For many years, aquarists have debated about the eating habits of plecos. Some claim that they are entirely herbivorous, while others argue that they are opportunistic feeders and will consume smaller tank mates. This debate has left many people confused about the nature of these fascinating fish.
“The truth is that plecos do have preferences when it comes to their food choices. While they primarily eat algae, they can also feed on various types of meaty foods. In this blog post, we’ll explore the ins and outs of Pleco’s dietary habits and provide you with a clear answer to the question: Do Plecos Eat Fish?”
If you’re curious about the eating habits of plecos, keep reading! By the end of this article, you’ll discover everything you need to know about what plecos eat and whether or not they pose a threat to other fish in your tank. Let’s dive in!
What Are Plecos?
Plecos, also known as plecostomus and suckerfish, are types of freshwater fish that belong to the catfish family. They are native to rivers and streams in South America and have become popular aquarium pets due to their unique appearance and behavior.
Introduction to Plecos
Plecos are known for their flat bodies and large mouths with rasping teeth. This combination allows them to scrape algae off rocks and other surfaces in their natural habitat. Their distinctive appearance makes them a fascinating addition to any aquarium.
Plecos come in various shapes, sizes and colors, making them highly sought-after among aquarium enthusiasts. These fish can live for up to 15 years or more when kept in optimum conditions.
Types of Plecos
There’s no shortage of pleco species to choose from, each boasting its own unique characteristics:
- Common Pleco: Often considered the standard variety of pleco, it has a brown body with light spots and a bushy tail fin. It can grow up to two feet in length.
- Bristlenose Pleco: A small, hardy species with a spiky appearance around its face and head. Bristlenoses are excellent at keeping algae under control.
- Rubber Lip Pleco: Named after its rubbery lips that help it hold onto slippery surfaces, this type of pleco is often seen with diamond-shaped patterns on its black or gray body.
- Zebra Pleco: A rare and expensive species due to its eye-catching black and white stripes. Zebra plecos require specific water parameters and need plenty of hiding spots.
Plecos as Aquarium Pets
If you’re considering getting a pleco for your aquarium, there are a few things to keep in mind. Plecos can be great additions to a community tank since they are peaceful and generally get along with other fish species. However, some larger plecos may become territorial as they grow older.
One common question among those interested in keeping plecos is whether or not they eat fish. While most plecos are herbivores that consume algae and plant matter, some large species have been known to nibble on smaller fish. It’s important to ensure that any fish added to the same aquarium with a pleco are of an appropriate size.

It’s also essential to provide plenty of vegetation and hiding places for plecos since they love to explore their surroundings. A good diet should consist of a combination of algae wafers and fresh vegetables like zucchini or cucumber.
Clean water is crucial for plecos to thrive, so regular tank maintenance is necessary. They prefer a pH level between 6.5-7.5 and temperatures between 72-82°F.
Plecos are a fascinating species to add to any aquarium due to their unique appearance and behavior. However, it’s crucial to understand the specific needs of the type of pleco you choose and ensure proper care to help them flourish in their new environment.
What Do Plecos Eat?
Plecos are a type of fish that belong to the Loricariidae family. They are known for their ability to eat algae, which is why they are often called “algae eaters.” But do plecos eat other types of food as well? In this article, we will explore the natural diet of plecos and discuss how to feed them in captivity.
Natural Diet of Plecos
In the wild, plecos primarily feed on algae, but they also consume small crustaceans and insect larvae. They use their strong jaws and teeth to scrape algae off rocks and other surfaces in the water. Plecos can digest both plant and animal matter because they have a unique digestive system that allows them to break down tough cellulose found in plants.
Some species of plecos also feed on wood. These fish have specialized digestive enzymes that help them extract nutrients from the decaying wood. Wood-eating plecos are commonly referred to as “pleco loggers.”
Feeding Plecos in Captivity
Feeding plecos in captivity can be challenging, especially if you want to provide them with a balanced diet. While they require a lot of algae in their diet, too much of it can lead to health problems such as bloating and constipation. It is essential to provide them with a variety of foods to keep them healthy.
One way to feed your plecos is to offer them fresh vegetables such as zucchini, cucumber, lettuce, and spinach. You can chop the vegetables into small pieces and drop them directly into the tank. Another option is to attach a vegetable clip or suction cup to the side of the tank and place the vegetables there. This method prevents the vegetables from sinking to the bottom of the tank and rotting.
In addition to vegetables, you can supplement your plecos’ diet with meaty foods such as shrimp, krill, and bloodworms. These foods are high in protein and will provide your fish with the necessary nutrients they need to thrive. Remember not to overfeed your plecos because they have a slow metabolism and cannot digest food quickly.
Commercial Pleco Food
If you don’t have time to prepare fresh food for your plecos or want to ensure they get a balanced diet, you can purchase commercial pleco food. There are many options available on the market, including pellets, wafers, and flakes specifically designed for plecos. These foods contain essential vitamins and minerals that will keep your fish healthy.
When purchasing commercial pleco food, make sure to read the ingredients carefully. Some commercial foods may contain fillers or additives that can be harmful to your fish. Look for products made with high-quality ingredients and avoid those containing too much wheat, corn, or soy.
Supplemental Foods for Plecos
In addition to their main diet of algae and vegetables, plecos also enjoy supplemental foods such as fruits and nuts. You can feed them small amounts of apples, pears, bananas, and berries. Nuts such as pecans, almonds, and walnuts can also be given as treats.
Another favorite treat among plecos is frozen peas. Simply thaw out some frozen peas and remove the outer shell before feeding them to your fish. This treat provides fiber and helps prevent constipation.

Plecos need a variety of foods in their diet to stay healthy. While they primarily feed on algae in the wild, it is essential to supplement their diet with fresh fruits and vegetables, meaty foods, and commercial pleco food. By providing them with a balanced diet and not overfeeding them, you will ensure your fish live a long and healthy life.
Do Plecos Eat Other Fish in Your Tank?
Plecos, or plecostomus, are a type of freshwater fish that have become increasingly popular among aquarium enthusiasts. As herbivores, they prefer to feed on vegetables and fruits such as zucchini, cucumber, or even bananas. However, there have been instances where plecos have attacked and eaten other fish in the tank.
When Plecos Attack Other Fish
Despite their docile nature, plecos may attack and eat other fish when they feel threatened or stressed out. This can happen when the tank is not big enough for all the inhabitants, or if the water quality is poor. Under these conditions, plecos may behave aggressively towards other fish, especially those who are smaller or weaker than them.
“Plecos can be very territorial, particularly when they do not have enough space in the tank,” warns Jeffrey C. Howe, an expert in aquatic life at the University of Massachusetts Amherst. “It’s important to provide your pleco with enough hiding places and plants so that they don’t feel like they need to defend their territory.”
Moreover, plecos tend to become more aggressive during breeding season, which usually occurs between late fall and early spring. During this time, male plecos may become territorial and fight over females, resulting in injuries or death of other fish in the tank.
Types of Fish That Plecos Eat
While plecos are mostly known to consume algae and plant-based foods, some species have been observed feeding on small fish and shrimp in the wild. These include the Hypostomus spp., Pterygoplichthys spp., and Farlowella spp. varieties of plecos.
It’s important to note that not all plecos eat fish. According to Howe, “Many of the species commonly found in pet stores are not predators and can be safely kept with other types of fish.” He advises doing research on the specific species of pleco before introducing them into a community tank.
Why Plecos May Eat Other Fish
There are several reasons why plecos may resort to eating other fish in the tank:
- Hunger: If their diet is not varied or nutritious enough, plecos may turn to other sources of food such as smaller fish or shrimp.
- Stress: If the tank conditions are suboptimal, plecos may become stressed out and act aggressively towards other fish.
- Breeding season: During mating season, male plecos may fight over females and accidentally injure or kill other fish in the process.
- Territoriality: Plecos may become territorial if they feel like there’s not enough space or hiding places for them in the tank.
To prevent plecos from attacking and eating other fish in your tank, it’s important to provide them with adequate nutrition, environment, and space. Feed them a balanced diet consisting of both veggies and protein-rich foods, regularly clean the tank to maintain good water quality, and ensure that there are enough hiding spots and plants to create a peaceful and secure environment for all inhabitants.
What Should I Do If My Pleco is Eating My Fish?
Plecos, also known as suckerfish or algae eaters, are popular fish for aquariums. They are bottom-dwellers and are often used to clean up excess food and debris in the tank. However, some plecos may start eating other fish in the tank, causing concern for many aquarium owners. This can be a serious issue, especially if the pleco is larger than the other fish in the tank.
Separating Plecos and Other Fish
If your pleco is eating your fish, you should consider separating them from each other. You can do this by either transferring the pleco to a separate tank or moving the other fish to another tank. It’s important to note that plecos can become territorial, so it’s best to give them enough space in their own tank to avoid further conflicts with other fish.
You can also use dividers within the same tank to keep the pleco separated from other fish. To set these up, simply place an acrylic divider between the pleco and the other fish. This will create a physical barrier that prevents the pleco from attacking the other fish while still allowing them to share the same water supply.
Removing Plecos from the Tank
If you don’t want to or aren’t able to separate the pleco and other fish yourself, then remove the pleco from the tank altogether. Removing the pleco from the tank doesn’t necessarily mean getting rid of it but instead, finding it a new home outside of your current tank where it cannot harm other fish.
You may choose to donate the pleco to a local pet store or aquarium, sell it to other hobbyists or donate it to a friend who has a suitable habitat for the pleco. Alternatively, you can simply release it in a local pond or stream where it can thrive and live out the rest of its life without harming other aquatic animals.
Consulting an Aquatic Veterinarian
If your pleco is showing signs of aggression towards other fish in the tank, consulting with an aquatic veterinarian may be the best option. A veterinarian can help identify the root cause of your pleco’s behavior and provide recommendations on how to address the issue effectively
An experienced veterinarian will have a wealth of knowledge about common behavioral problems among aquarium fish species, including plecos. They may examine the tank or ask questions regarding the feeding habits, water quality and lighting conditions to determine any possible causes of aggressive behavior.
Rehoming the Pleco
If after seeking advice from an aquatic veterinarian, separating the pleco from other fish by using tanks/dividers seems impossible, then re-homing the pleco is the next option. This process involves finding someone who would want to take in the pleco as their own, without risking the health of their other fishes.
You can find a new home for your pleco through social media platforms such as Facebook fishkeeping groups or online forums dedicated to fish/breeding communities. There are also websites like Craigslist where people post aquarium-related advertisements.
“It’s important to keep in mind that plecos come in different sizes; some as small as 2 inches and others growing up to two meters (6.5ft). You should always make sure when selecting different fish species to cohabitate together, each inhabitant can get along peacefully,” said Kristen Laine, Vice President of PetSmart’s aquatics merchandising team.
If you suspect that your pleco has been eating other fish in your tank, try separating the pleco and other fish, remove the pleco from the aquarium or consult with an aquatic veterinarian to identify any possible behavioral issues that could be causing your pleco’s aggression. Re-homing the pleco may also be a viable option if none of these methods work. Keeping a healthy environment for all your fishes is important; therefore, you need to take action as soon as you can to protect them.
How Can I Prevent My Pleco from Eating My Fish?
Plecos are a popular type of algae-eating fish that some people keep in their aquariums. Regrettably, plecos have been known to eat other types of fish if they aren’t adequately fed or given enough hiding places. However, there are several ways you can stop your pleco from eating your other fish.
Feeding Your Pleco Adequately
One of the reasons why plecos may choose to eat other fish is because they’re feeling hungry. Therefore, ensuring you’re feeding them regularly and sufficiently could help curb their fish-eating behavior.
“Plecos should primarily be fed on fresh vegetables such as spinach, cucumber, and zucchini,” according to Aquarium Source. “But also require occasional meaty foods like brine shrimp or bloodworms.”
You could either feed your pleco in another corner of the tank, add food during your other fish’s inactive hours, or make sure you provide more than enough food for everyone present in the tank so the competing factor is eliminated.
Providing Hiding Places for Other Fish
If your pleco isn’t excessively hungry but loves chasing other fish, giving your non-pleco aquatic pets more nooks and crannies to hide may be necessary. The less interaction between all the different creatures in the tank, the better.
“To reduce aggression from plecos,” Aqua Movement advises, “make sure that your aquarium has plenty of structures for swimming and hiding.”
Adding more plants, rocks, decorations, pipes, and driftwood will give your other fish somewhere to retreat whenever the need arises. Such constructions also fulfill aesthetic purposes while making the fish feel extra comfortable. Lastly, separate sections within the tank can be useful for curbing pleco aggression, as well.
Adding More Fish to the Tank
This may sound counterintuitive, but adding some more fish to your current stock could decrease intra-species competition and feed rivalry.
“Plecos are not always aggressive towards other fish,” according to Pure Goldfish. “In fact, they generally prefer to stay out of trouble.”
If possible, incorporate species that swim at different depths or across exposed spaces so all the added animals get a chance to establish their spot in the ecosystem without causing any unnecessary wars.
Using Tank Dividers to Separate Fish
The strongest method of preventing pleco-fish violence is by physically separating the parties with tank dividers while still keeping them under observation. The size of your aquarium will largely determine whether this solution will work since it requires considerable space between each section, but the dividends might far outweigh the initial setup costs.
PetMD recommends: “If you have an especially dangerous or aggressive fish in community tanks, consider purchasing a breeding trap or isolation tank to keep them until they learn to share habitat space more peacefully.”
Also, bear in mind that plecos need enough oxygen, filtration, and free swimming space depending on their available population; otherwise, they become stressed and their risk for attacking other fish increases.
There’s no guarantee that your pleco won’t eat other fish now or again. However, proper care and attention can go miles toward minimizing such scenarios (or making sure they don’t occur altogether). Feeding adequately, providing hiding areas, adding compatible fish, and using dividers should do the trick.
