(Naucrates ductor)

Naucrates Jacks are fast growing and become quite large they should only be added to very large aquariums preferrably zoos or public aquariums. They are very active, strong fish that will bully other tank mates careful consideration should be given before adding this fish to home aquariums. Provide wide open swim areas with minimal rockwork. Jacks are often found near sandy, muddy bottom regions. Juvenile Jacks are often found swimming under floating seaweed. Adults will generally swim alongside predatory fish feeding on their scraps. Juveniles usually travel in schools but as they mature they travel in pairs or even singly.

The Pilotfish is also sometimes known as the Pilot jack. They are not typically seen in the aquarium trade due to their large size and predatory behavior. Pilotfish have a distinctive appearance, with a silver-colored elongated body and a black spot on their head behind their eyes. Pilotfish are known for their symbiotic relationship with sharks, often swimming alongside them in the wild. They can grow up to 2 feet in length.

We recommend a minimum aquarium size of 360 gallons or larger for this species.
