No, piranhas are not native to the Nile River. Piranhas are primarily found in the freshwater rivers of South America, particularly in the Amazon basin. While the Nile River is home to a variety of fish species, including Nile perch and catfish, piranhas do not inhabit these waters.
There have been occasional reports of piranha sightings in some non-native regions, usually due to the pet trade or aquarium releases. However, these instances are rare, and piranhas do not establish sustainable populations outside their native range. Therefore, visitors to the Nile can enjoy the diverse aquatic life without the concern of encountering piranhas.
