no they don`t eat all kinds of fish!
Caimans, anacondas, otters, herons, and giant fish will eat piranhas.
Giant Otters are carnivores and, along with Black Caimans and Jaguars, are one of the apex predators of the Pantanal. Giant Otters are normally piscivores, meaning they normally eat fish, and are capable of killing fish up to the size of arapaima. However, Giant Otters are very tough predators and are capable of killing predators of the size of 3 meter Yelllow Anacondas and Spectacled Caimans.

Yes they eat fish.
Giant otters eat piranhas primarily because they are a readily available and nutritious food source in their aquatic habitats. These otters are skilled hunters, utilizing their cooperative social structure to catch fish, including piranhas, which are abundant in the rivers and lakes of South America. Additionally, piranhas provide a high-energy meal that supports the otters’ active lifestyle and helps them sustain their large size.
It depends on what "giant fish".
Fish, mainly.
