What are good tank mates for Pacu?

* Oscars * Cichlids (a green terror cichlid would go great with one)

* Parrot fish (that is just as equally large as the Pacu) * Red Tinfoil Barb Fish * Plecos (but has to be plecostumus, the large ones) * Red Hook Silver Dollar Fish

There are numerous other aggressive, semi-aggressive freshwater fish that Pacus can be good tank mates with. Ask your local pet shops or aquarium. Make sure the Oscars aren't really aggressive.
