What Do Pacu Fish Eat?
Animals to Meet – Aquarium Animal’s Behavior Pacu (Colossoma macropomum) are South American freshwater fish that are closely related to piranhas but have some significant distinctions: Pacu are vegetarians with teeth that are astonishingly similar to human teeth! There are many fish species generally known as pacu.
Eating Habits Pacu consume mostly flora and insects, eating on plant materials in rivers and seeds, nuts, etc. that fall from trees into rivers. They possess strong jaws. Range Native to South America, but widespread in Puerto Rico and other U.S. states. Conservation Efforts Pacu are not endangered. They are cultivated and consumed globally.
Animal Facts Despite having square, straight, molar-like teeth, pacu have an extremely powerful bite. Pacu were once considered acceptable for home aquariums; but, because to their rapid development and large size, it is now believed that they do not make excellent pets.
What are pacu fish fed?
To maintain the health of your red-bellied pacu in captivity, you must offer it a diversified diet of herbivore pellets or floating sticks as well as an abundance of fresh fruits and vegetables. The most likely vegetables consumed by red-bellied pacus ae are spinach, lettuce, peas, zucchini, cabbage, and carrots.
What do pacu fish consume? Pacu fish in the wild ingest foods such as nuts, fruits, and seeds. They will wait for their prey to fall from tree branches or swell in adjacent flood or marsh water. As previously stated, they will consume smaller fish when food is low, although they are predominantly herbivorous.
Pacu fish in captivity are typically fed fish pellets along with fresh fruits and vegetables. Pacu fish are able to consume spinach, lettuce, apples, bananas, peas, grapes, and carrots. Their human-like teeth enable them to consume the same foods as humans. Pacu fish can be given meat in captivity, however anecdotal evidence shows that feeding them an excessive amount of worms or shrimp may cause them to become finicky eaters.
The general perception is that it is comparable to feeding a toddler an excessive amount of junk food.
What fish are compatible with pacu?
Adults are solitary, however they are not hostile toward tank mates. However, the adolescents are more disruptive and violent. Adults consume whatever tiny fish they can swallow, but they pose little threat to larger species. Any medium- to large-sized nonaggressive species, such as herbivorous catfish, can suffice as pacu tank mates (like sailfin pleco ).
It will collect food scraps from the bottom of the tank. The ideal tankmates for pacu are fish of the same size (oscar fish, green terror, jaguar cichlid), otherwise they should be kept alone. As for the little fish, they are considered food, so do not house pacu with them. It may become a pleasant, responsive pet if given the correct tank size and sufficient care.
However, caution should be used when storing it in the tank. Although the majority of the fish’s diet consists of plant matter, its powerful teeth, which can fracture extremely hard seeds and nuts, pose a grave threat.

How can the gender of a pacu fish be determined?
Spawning pond or aquarium Male and female pacu Injector and soft canula tube Petri dishes Assistant Pipette Miniature glass bottles 60-gallon Zooplankton fry aquarium The red-bellied pacu is endemic to South American rivers. Due to their mature size of 30 inches, these huge vegetarian fish normally do not breed in captivity.
- Pacus have been coaxed to spawn using hormones at research facilities.
- The pointed back and anal fins of adult male pacus are distinguishing characteristics.
- The red tint on the abdomen of red belly pacu males is likewise more vivid.
- Stop feeding the breeding fish a day or two before injecting pituitary extract to induce spawning.
Inject the female pacu with a half teaspoon of carp pituitary extract for every 2.2 pounds of fish weight. Inject into the dense muscular mass on the fish’s shoulder. One can acquire pituitary extract from an aquatic research institution. Four-and-a-half to five hours following the initial injection, provide a second dosage of pituitary extract to the same female.
- At this time, inject a dosage of two and a half tablespoons per every 2.2 pounds.
- Inject the male shortly after administering the second injection to the female.
- Inject male fish with a half teaspoon for every 2.2 pounds.
- After the second injection, observe the female pacu from above five to six hours later.
A pregnant female will seem physically laden with eggs. Place the pregnant female on a moist towel after removing her from the water. If necessary, get a help to hold the fish. Before restricting the fish, the helper should dampen his hands. To retrieve eggs from the fish, insert the soft canule tube linked to the syringe into the vent of the pacu and pull very gently on the syringe plunger.
- Place these eggs in a Petri dish and fill the dish with dechlorinated water.
- This quantity should not exceed one-third of the volume of the egg mass in the dish.
- Place the male fish on a moist cloth after removing him.
- If necessary, get a help to hold the fish.
- Before restricting the fish, the helper should dampen his hands.
Apply adequate force to the abdomen of the fish in order to extract sperm from the vent. Place a Petri dish against the body of the fish to collect sperm or milt. Obtain the milk using a clean pipette. Apply up to 10 drops of milk per 150 milliliters of egg mass.
- Use a clean feather to combine the colostrum and the eggs.
- After 15 to 20 seconds, add a tiny amount of more water to the dish and gently shake it again.
- The fertilized eggs are placed in little glass jars containing water from the adult fish’s aquariums.
- Observe the process of hatching in roughly 48 hours.
Beginning on the third day after hatching, feed the hatchlings zooplankton obtained from an aquatic research center. After eight to ten days, the fry should be transferred to rearing tanks. Introduce a fish food powder at this time. Three times each day, provide only as much food as the fry can ingest in 10 to 15 minutes.
Although some species of pacu resemble piranhas in appearance, they are herbivorous and an exceptionally peaceful species of fish. Pacus breeding in a home aquarium is extremely difficult and little is known about the subject.
Can pacu and piranha coexist?
Black pacu – Temperature: 24-27 C Tank capacity: 650 gallons Adult size: 40 inches Temperament: peaceful Diet: omnivores Piranha fish are compatible tankmates with black pacu. Although they enjoy meat-based meals, they frequently prefer plant-based options.
Nonetheless, they will consume tiny fish if they are starving. Therefore, ensure that you provide it with nutritious food. Vegetables, live and frozen food, such as blood worms, and commercial items should be included. Black pacus, unlike other pacu, are docile and flourish with other tankmates. They may reach a maximum size of 108 centimeters, nearly outgrowing the majority of indoor tanks.
Due to their human-like teeth, they have been observed cracking nuts and biting prey to the bone. The male is more vibrantly colored than the female. Additionally, sailfin Pleco, black pacu, and Bristlenose Pleco are suitable.
