Wild-caught pacu can be found in multiple tropical freshwater river systems, especially the Amazon and Orinoco basins. They are usually sold, however, in some commercial aquaculture due to their large size and high meat yield.
Pacu fish are raised in aquaculture systems throughout the world because they can adapt to various aquatic conditions. They are commonly sold to markets and restaurants that serve people who like trying unusual or exotic fish. Pacu has a nutty flavour and is often compared to tilapia and catfish.
Some pacu fish sale are sold to individuals and companies in the aquarium trade, where they are considered attractive and distinctive fish. Members of the genus Colossoma can reach lengths of three feet or more in captivity, while Piaractus can reach approximately two feet in length, making them large fish specimens. They also have striking looks, including their silvery bodies and unique shapes. While smaller pacu species are preferred in the aquarium trade, juvenile pacu are frequently sold by pet stores and online retailers.
There is a growing interest in using pacu as a sustainable fish feed source in food production, particularly in Africa and Southeast Asia, owing to their quick growth and ability to consume plant-based diets.
Pacu fish are closely related to piranha and have strikingly different appearances. Piranhas have sharp teeth that are made to cut and eat meat, while pacu have flat, human-like teeth used to crack open nuts and seeds. This is how the name pacu was derived; it comes from a Tupi word that means “splitter”. Adult pacu can get much longer and bigger than their piranha cousins. They normally reach a length of about 18 inches, while some exceptional cases have even reached three feet in length. Pacu usually sports a deep, laterally flattened body with a forked tail. They have a metallic, greenish-grey to silver coloration on their body. Juvenile pacu look a bit similar to piranha, but as they grow, they start looking more like members of the carp family.
Pacu fish are native to the freshwater rivers and floodplains of the Amazon and Orinoco basins. Because of their ability to adapt to diverse aquatic environments, they have been introduced into other tropical regions around the world. Pacu are highly versatile and resilient fish. They thrive in water with a range of pH and a variety of dissolved oxygen levels. They can even survive in brackish water due to their ability to adjust to different salinity levels.
Pacu are peaceful fish with a dietary difference that distinguishes them from piranha. While piranhas are carnivorous and eat meat, pacu are omnivores with a preference for a plant-based diet. They feed on fruits, nuts, seeds, and, over the years, have developed a taste for vegetation. Their strong, flat teeth are specifically designed for crushing hard food items such as nuts. This contrasts with the triangular, razor-sharp teeth of piranhas, which are used for cutting and tearing flesh.
Pacu are social creatures that prefer to live in groups, particularly when they are young. They tend to be more solitary as they grow and become larger. Adult pacu are often kept separate from smaller fish in aquarium settings because of their size and potential to disturb other inhabitants. Pacu are known to be visually striking and lively and can develop entertaining personality traits. Some pacu may be playful or even interactive with their owners. Wild pacu are migratory fish that travel long distances across river systems in search of food. They are known to spawn during the rainy season when the rivers overflow. This provides ample space for their eggs to develop in the flooded forest regions.
Pacu fish belong to two genera, Colossoma and Piaractus, in the family Characidae. The species often included in the genus Piaractus, such as the red belly pacu and blue, red belly pacu, are more closely related to the piranhas and are considered more aggressive. The species in the genus Colossoma, like the black pacu, are typically larger and more docile.
Pacus have the potential to grow quite large. They can reach up to three feet in length in ideal conditions. Most species, however, typically grow to about 18 inches long. Size directly depends on the species and the environment they are raised in. Pacu fish that have been raised in captivity tend to grow faster than those in the wild. This is mainly due to factors like availability of food and optimal living conditions.
Despite being tropical fish, pacu are relatively hardy. They are able to survive in a wide range of water conditions. This makes them highly adaptable. They can thrive in water with varying levels of pH and dissolved oxygen. They have even been recorded to survive in waters with brackish salinity. Although pacu prefer warm, well-oxygenated freshwater, their adaptability allows them to live in environments that may not be ideal for other species.
Pacu fish are typically well-packaged around ice or gel packs in a styrofoam box. This ensures they stay cool during transport. Their packaging includes well oxygenated bags to keep them alive throughout long-distance transport. There is also the option of using a plastic bag with a mixture of oxygen and carbon dioxide. This helps to pacify the fish and make them less active, thus reducing the need for oxygen.
Pacu meat is highly regarded in some regions for its mild, versatile flavor and firm texture. This makes it a popular choice among those who enjoy trying out new and exotic delicacies. It is frequently compared to tilapia or snapper, which makes it a good substitute in various recipes. It can be prepared in multiple ways, such as grilling, baking, frying, or making into fish tacos and soups. This makes it a popular fish among restaurants and markets in areas where pacu are available.
For fish enthusiasts, juvenile pacu are often acquired from pet stores or fish suppliers. They then raise them in home aquariums. Pacu are typically sold as juvenile fish in the aquarium trade. It is important to note that pacu require large aquarium environments to accommodate their size. This is because pacu can grow quite large, with some reaching lengths of up to three feet. For this reason, pacu are recommended to be kept in public aquariums or specialized facilities rather than home fish tanks.
Pacu fish are environmentally friendly species to farm. This is because they primarily eat plant-based diets. They can be raised on low-cost feed, reducing the overall cost of fish farming. With growing interest in plant-eating species like pacu, there is potential for more sustainable aquaculture practices, particularly in regions where other protein sources are scarce.
Pacu are often used in scientific studies to help scientists learn more about fish biology, behavior, and ecology. Some studies may focus on their ability to adapt to different environments. Others may study their feeding habits and how they influence their environment as seed dispersers. Educators frequently utilize pacu in aquarium programs to teach students about fish care, aquatic ecosystems, and the importance of conservation.
This fish is still popular among indigenous peoples in the Amazon because it was historically an important food source. They can still be found in traditional markets in some regions today, where they sell the fish whole, fillet, or in other forms.

Red belly pacu are smaller and easier to manage, so they are the more popular choice for home fish enthusiasts.
For buyers looking for pacu fish for sale, they should consider the seller's capacity to provide the necessary environment to transport the fish properly. The seller should be able to provide a well-oxygenated environment with stable water parameters, such as pH and temperature to ensure the fish survive during transportation. For buyers intending to sell the fish to restaurants or markets, they should purchase a fish that meets culinary standards for food safety. Fish that are harvested legally and ethically promote sustainability in the environment.

This will help the buyer maintain a stable profit margin for himself or ensure he has a consistent supply for his market. Consider the logistics and costs to ensure the fish can be transported without added costs that will negatively impact the budget. Buyers should also think about the minimum order quantity and the requirements for importing the fish legally if buying from other countries.
A1. People get the piranha and pacu fish confused because they look a bit similar. However, they are indeed different. Buyers should check for wholesaler fish that look active and eat readily. Fish that are tired and don't have the strength to move around or refuse to eat are signs of unhealthy fish. Buyers should also buy fish that have a clear skin with no signs of disease.
A2. Pacu fish are usually susceptible to the same diseases as other freshwater fish. These include ick, fin rot and fish tuberculosis. They can also be affected by external parasites like ticks and leeches. Other internal parasites that infect pacu fish are mosquitoes and waterslides.
A3. Pacu fish usually reach sexual maturity at the age of two years. However, it all depends on how they are raised and their species. For instance, wild pacu fish become sexually mature between the ages of three to four years. This is the same as red belly pacu. They take an extra year to attain maturity because they grow slower than the black pacu fish.
A4. Buyers use piranha fish in making soups, curry and fish stew. They also eat it fried, grilled or baked. When the meat of the fish is mixed with spices and flavors, the strong taste of the meat reduces and it can almost be eaten comfortably. There are some places that eat the pacu fish in a dangerous way by frying its flesh together with its poisonous egg because they believe it improves their sexual prowess.
A5. Occasionally, there may be legal restrictions on the exporting of pacu fish, especially from countries that are trying to care for their endangered species. Therefore, buyers must research the laws and regulations in their country. This will enable them to understand exporting pacu fish and file the necessary paperwork to avoid legal consequences.
