Common name: Yellow and blueback fusilier

General information

The Redbelly Yellowtail Fusilier, Caesio teres, is a vibrant and active fish that adds a splash of color and movement to any marine aquarium. Known for their striking blue and yellow coloration, these fish are a favorite among aquarists who appreciate schooling species. They are found in large schools in the wild and can bring a similar dynamic to the home aquarium when kept in groups.

Care

Yellowtail Fusiliers are relatively hardy and can adapt to a range of aquarium conditions. They require a spacious tank with plenty of open swimming space to accommodate their active swimming habits. A diet of small meaty foods, such as mysis shrimp and finely chopped seafood, will help maintain their color and health. It's important to provide a varied diet to ensure proper nutrition.

Reproduction

In the wild, Caesio teres spawns in large aggregations, releasing eggs and sperm into the water column where fertilization occurs. While breeding them in captivity is challenging, understanding their natural spawning behavior can be beneficial for potential breeding programs.

Habitat

Redbelly Yellowtail Fusiliers are commonly found in the Indo-Pacific region, from the Red Sea and East Africa to the Line Islands and Tuamoto Islands, north to southern Japan, and south to New Caledonia and the Austral Islands. They inhabit clear lagoons and seaward reefs, often seen at depths ranging from the surface to about 50 meters.
