Two Barred Rabbitfish - Fiji

Siganus doliatus The Two Barred Rabbitfish, also known as the Barred Spinefoot or Scribbled Rabbitfish, is a peaceful, reef-safe species admired for its striking coloration and algae-grazing behavior. Its body is pale bluish-grey to whitish, marked with two bold diagonal brown bars—one through the eye and another just behind the head—along with fine blue lines on the head and upper sides, and bright yellow dorsal and caudal fins, creating a vibrant, eye-catching appearance. In the wild, Two Barred Rabbitfish inhabit coral-rich lagoons and seaward reefs, typically at depths of 2–15 meters. Juveniles often form schools, while adults are usually seen in pairs or small groups. They are herbivorous, feeding primarily on benthic algae, seagrasses, and macroalgae, helping maintain reef health. In the aquarium, they thrive in well-established systems with plenty of live rock for grazing and shelter. While generally reef-safe, they may occasionally nip at soft corals or LPS if not provided enough algae-based foods such as nori, Spirulina, or other vegetable matter. Frequent feedings help maintain their health, coloration, and natural grazing behavior. Growing to about 10 inches (25 cm) in length, the Two Barred Rabbitfish is a striking and functional addition to community and reef aquariums, offering both beauty and natural algae control for a balanced marine environment.
