It all depends on the size of the turtle and the pacu. If the pacu is at least the same size as the turtle then it is okay for them to be tank mates. The worst that would happen is that the turtle would be able to nip on the fins of the pacu which will eventually grow back. aquatic turtles produce a lot of waste so make sure that your filter is rated for twice the gallons that your tank holds. The species of turtle and the age of the turtle will make a difference as well, for example red eared sliders are more herbivorous when they get older, past 5yrs, while snapping turtles will have a higher chance of injuring/killing your pacu. It is very important that both the aquatic turtle and the pacu are housed in a large tank/pond because they both get big. This will decrease the chances of them encountering each other.
Experienced aquarists never mix fish with Amphibians or Reptiles because they know they are heading for failure. It is recommended that many Reptiles (depending upon species) be kept in a set up where they can actually get out of the water and dry out a bit and sunbake too sometimes. As the other person above wisely says, the Turtle could also damage the fish by biting chunks out of it.
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.
Yes a 3 inch pacu can live two 5 to 6 inches oscar!!!!!
both pacu and piranha eat live meat and they both can have red bellies too. the real difference is between their jaws, nose and teeth. piranha has a produting lower jaw while pacu has a round mouth. pacu's nose is button shaped but piranha's nose is unmistakable. and piranhas have much larger teeth than pacus.
5-15 years generally
Pacu are not as aggressive as Piranhas but can be if threatened.
on admission into the pacu, 30 minutes after admission into the pacu, and at 60 minutes
I think you mean Pacu: http://en.wikipedia.org/wiki/Pacu
Amazon Basin. West Indies. South Central Asia. (They are starting to spread in Florida.)
Not all species that are piranha-like are carnivores. The Pacu-Pacu generally eat seeds that fall into the water and they look like piranhas. The Pacu-Pacu can also be kept in tropical home aquariums as a species tank.
A pacu is any of several South American freshwater fishes related to the piranha.
Red belly pacus are the same thing as a black pacu and it all depends on how your pacus act.
