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.
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.
Well they are vegetarian. They would eat small fish that could fit in their mouth if they were hungry also they are opportunist fish
It is never right to put Amphibians in with fish. The amphibian will poison the water.
Most turtles will eat fish that they are housed with, unless the fish are much much larger than the turtle.
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.
Adult red belly pacu and Oscars are both large and aggressive fish that may fight if housed together in a tank that is too small or lacks enough hiding spots and territories. It is not recommended to house adult red belly pacu and Oscars together unless in very large tanks with plenty of space and hiding spots to reduce aggression. Monitoring their behavior closely is important to prevent aggression and potential injuries.
The normal water temperature for red belly pacu fish is typically between 72-82 degrees Fahrenheit (22-28 degrees Celsius). It is important to maintain a stable temperature within this range to ensure the health and well-being of the fish.
