Animals A-Z

Type of Animal: Fish (marine)
Habitat: Shallow coral reefs, seagrass beds, and sheltered lagoons in the Banggai Archipelago, Indonesia.
Diet: In the wild, they feed on plankton, small crustaceans, and tiny invertebrates.
Size: Adults grow to around 8 cm (3 inches) in length.
Conservation Status: Typically 4-5 years in the wild, with a similar lifespan in captivity.

• Mouthbrooding Fathers: In a unique reproductive behaviour called mouthbrooding, the male Banggai cardinalfish carries fertilised eggs in his mouth until they hatch, protecting them from predators and environmental dangers. This ensures a higher survival rate for the offspring.
• Endemic and Vulnerable: The Banggai cardinalfish is endemic to the Banggai Archipelago, meaning it is found nowhere else in the world. This limited range makes the species especially vulnerable to overfishing and environmental changes.
• Conservation Efforts: Due to its over-collection for the aquarium trade, conservation efforts are underway to breed Banggai cardinalfish in captivity and protect its natural habitat. Sustainable practices are critical to preserving this species in the wild.
• Symbiotic Relationships: Banggai cardinalfish often form close relationships with sea urchins, using their long spines as protection from predators. Schools of these fish can be seen hovering around the urchins, blending in with the spines for added safety.
• Nocturnal Lifestyle: Banggai cardinalfish are primarily nocturnal, becoming more active at night when they hunt for food and avoid predators. During the day, they prefer to stay close to hiding places among coral or seagrass.
