In this article we will talk about the Pacu fish (Myleus Pacu) which undoubtedly has a place in the list of the rarest fish in the world.
This rare animal looks quite similar to the piranhas and this is because it is related to them, as it belongs to the caracids family.
However, despite being a family of piranhas, the Pacu fish is not considered a dangerous or carnivorous species.
Pacu fish characteristics
As we mentioned at the beginning of the article, the Pacu fish looks quite similar to a piranha, its body is rounded, narrow on the sides and completely covered with scales.
In addition, it has peculiar bulging eyes and can reach a significant size averaging 70 cm and even more. Actually, its size will vary if it is a fish in captivity or if it is in its natural habitat.
As for its weight, this rare animal can reach 15 kilos or more depending on its development and feeding.
Its large size, weight and taste make it a favorite of people in certain areas.
Its body is silvery with orange colorations, although as with other characteristics already mentioned, its color also changes, but this time according to the species. What is almost a rule is that its anal fin is black.
An interesting detail is that in this species there is a marked sexual dimorphism. Females outnumber males in size and even their body is more robust.
In addition, males develop a larger dorsal fin and their body is more colourful.
Something that characterizes the Pacu fish is its peculiar teeth, very similar to those of humans. By the way, although this fish is not a violent animal, its bite is potentially harmful because it has an outstanding strength in its jaws.
On the other hand, this rare fish has a fairly well-developed sense of smell. It is sensitive to different odors, such as animal fat, mollusks, blood, insects and even urine.
Behavior of this Strange Fish
The Pacu fish can usually be observed in schools of 5 to 7 fish and is not considered a threat to humans as it is characterized by peaceful behavior.
However, there have been biting accidents, but this has occurred only on rare occasions because the Pacu fish is not a carnivorous animal.
Also, there is no problem with when it is time to live with other fish. It adapts perfectly to the companions with whom it must share space.
This rare fish is widely used to decorate aquariums with such beautiful fish. Because to have it only needs to take into account certain basic care.
Habitat of this Rare Fish
The Pacu fish is a freshwater animal found mainly in the Amazon River. However, this migratory species can be found in several rivers around the world.
Although the Pacu fish is usually exported to other places because of its taste and because it makes an excellent dish, in some regions it has come to be considered a threat to the ecology because it is considered to alienate native species by taking away their habitat.
What does the Pacu Fish eat?
Because the Pacu fish has powerful teeth, it can feed on things that only a few fish use for food.
For example, it eats fruits with shells, such as nuts or hard seeds. However, their diet is mainly made up of vegetables.
In this sense, those who keep these animals in aquariums usually feed them with lettuce, carrots, apples, bananas, peaches, squash, cabbage, peas, among others.
Although the Pacu fish is not considered a carnivorous animal, it is clear that it is omnivorous and therefore on rare occasions can feed on other fish much smaller than it.
This great variety in their diet is what allows the Pacu fish to feed on virtually everything that happens in front of him and thus get a great weight and size.
Pacu Fish reproduction
Because the Pacu fish are usually in schools, reproduction is usually quite numerous.
The reproduction of this fish is migratory, as they move to smaller streams to spawn.
It is normal that this fish reproduces in summer because they get the right temperature for their small eggs.
Something striking is that the female leaves the eggs and the father will take care of them for more than 72 hours until the hatching occurs.
