General information

The Orange-spotted Rabbitfish, also known as the Gold-spotted Spinefoot, is a colorful and peaceful species that is well-suited for larger community aquariums. With its bright yellow body and distinctive orange to reddish spots, it adds a splash of color and activity to any tank. This species is known for its venomous dorsal spines, which it uses for defense. In the wild, Siganus guttatus is often found in schools, grazing on algae in shallow waters.

Care

Orange-spotted Rabbitfish are herbivorous and require a diet rich in vegetable matter, including marine algae and prepared foods that contain spirulina or other plant-based ingredients. They are generally peaceful but can be territorial with their own kind or similar-looking species. A larger tank with ample swimming space and hiding places is recommended. They are sensitive to water quality, so regular water changes and good filtration are essential.

Reproduction

In the wild, Siganus guttatus spawns in groups, releasing eggs and sperm into the water column where fertilization occurs. In the aquarium, breeding is rare, but environmental stability and a well-maintained tank can encourage spawning behavior. The larvae are planktonic and would require specialized care if one intends to raise them.

Habitat

The Orange-spotted Rabbitfish is native to the Indo-Pacific region, from the Red Sea and East Africa to the Philippines, north to southern Japan, and south to New Caledonia. They are typically found in coastal reefs, lagoons, and seaward reefs, often in areas with abundant algae growth, at depths ranging from 1 to 30 meters.
