1. Zooplankton: Ballyhoo are planktivores, meaning they largely feed on tiny, drifting organisms found in the ocean's water column. Their diet includes various zooplankton, such as copepods, amphipods, krill, and fish larvae.
2. Small Crustaceans: Ballyhoo often target small crustaceans as part of their diet. This includes shrimp, crab larvae, and other minute crustaceans found near the water's surface.
3. Small Fish: Ballyhoo can be occasional predators of smaller fish species. They hunt small, easily accessible fish such as anchovies, sardines, and other juvenile fishes that inhabit the surface waters.
4. Insects: Depending on the location and habitat, ballyhoo may also ingest insects that fall into the water from overhanging vegetation or are blown by the wind. These insects can serve as an occasional food source.
It's important to note that the specific food choices of ballyhoo may vary depending on factors such as the local ecosystem, availability of prey, and competition from other fish species. However, zooplankton, small crustaceans, and smaller fish generally make up the primary components of their diet.
