The Magnificent Rabbitfish (Siganus magnificus), also known as the Magnificent Foxface or Andaman Foxface, is a marine species belonging to the Siganidae family. This species is notable for its striking coloration and is native to the eastern Indian Ocean, particularly the Andaman Sea.
Key Information
• Small fish safe: ✅ Yes (generally peaceful)
• Small invertebrate safe: ⚠️ With caution (may nip at corals if underfed)
• Coral safe: ⚠️ With caution (ensure adequate feeding to prevent coral nipping)
• Minimum tank size: 475 litres (125 gallons)
• Adult size: Up to 24 cm (9.4 inches)
• Diet: Primarily herbivorous, feeding on algae; may consume small invertebrates
• Be aware of: Venomous spines; handle with extreme caution
Appearance and Colouration
Siganus magnificus exhibits a distinctive and vibrant coloration:
• Body: The anterior half is white with a prominent black diagonal band running from the dorsal fin through the eye to the mouth. The posterior half is dark brown to black.
• Fins: Pectoral, anal, and caudal fins have bright yellow margins, while the soft-rayed part of the dorsal fin has a pale red margin.
Natural Habitat and Behaviour
The Magnificent Rabbitfish inhabits coral reefs in the eastern Indian Ocean, particularly around the Andaman Sea, including areas like the Mergui Archipelago in Myanmar and the Surin and Similan Islands in Thailand. They are typically found at depths ranging from 2 to 20 meters, often among branching corals.
• Social Structure: Adults are commonly observed in pairs, while juveniles tend to be solitary and seek shelter within coral structures.
• Diet: Primarily herbivorous, feeding on algae, but they may also consume small invertebrates.
Aquarium Care
While not as commonly kept as some other rabbitfish species, the Magnificent Rabbitfish can adapt to home aquariums if provided with appropriate care:
• Tank Size: A minimum of 475 litres (125 gallons) is recommended to accommodate their size and swimming needs.
• Diet: Provide a diet rich in algae to mimic their natural feeding habits. Supplement with herbivore-friendly foods to ensure nutritional balance.
• Tank Mates: Generally peaceful, they can be housed with other non-aggressive species. However, monitor interactions to ensure compatibility.
Due to their venomous spines, caution is advised during tank maintenance to prevent injury. Ensure that all tank inhabitants are compatible and that the environment is enriched to promote natural behaviors.
