Well they are vegetarian. They would eat small fish that could fit in their mouth if they were hungry also they are opportunist fish
Pacu are not as aggressive as Piranhas but can be if threatened.
I think you mean Pacu: http://en.wikipedia.org/wiki/Pacu
There are several differences between the pacu and the piranha fish. One is their jaw alignment, their teeth are different. Their sizes are generally also different, a grown pacu is larger than a piranha.
Nothing you dumb person.
Piranhas are in the subfamily Serrasalminae. Other fish that are in this subfamily and that are closely related to the Piranha are Pacu and the Silver Dollar
The domain of a pacu fish is Eukarya, as it is a eukaryotic organism with cells that contain a nucleus and other organelles. Pacu fish belong to the family Serrasalmidae and are primarily found in freshwater habitats in South America. They inhabit rivers, lakes, and floodplains, playing a role in their ecosystems as herbivores and seed dispersers.
Well, like most endangered animals by other animals and humans kills them and the young.
Pacu are a type of piranha. They do have scales, like most fish, as well as fins.
Pacu are primarily vegetarians. They can eat meat, however it is not necessarily good for them. Meat from mammals is high in fat, and is more difficult for the pacu to digest. It also is less nutritious for them than vegetables, fruit or fish food. Shrimp is perfectly fine for a pacu to eat, however I would not turn it into his primary diet. I feed mine algae wafers, and the occasional peas, lettuce, and carrots. Mine also eats some of the regular fish flakes that I feed the other community fish in the tank with him.
It is never right to put Amphibians in with fish. The amphibian will poison the water.
There are several species known colloquially as Pacu fish. They are all related to and larger than the Pirahna. They get VERY BIG. Over a metre and weighing in at over 60lbs. To the best of my knowledge there is no sexual dimorphism in aquarium specimens. I would assume that in adult fish the female is the one that lays the eggs.
Most turtles will eat fish that they are housed with, unless the fish are much much larger than the turtle.
