Appearance

Moluccan Cardinalfish are small, slender fish with a distinctive two-tone coloration: red-orange on the upper body and silvery-white on the lower half, with a characteristic dark stripe running from snout to tail. The head is slightly oversized relative to the body, and they possess large eyes adapted for nocturnal feeding.

Diet and feeding

Feed small carnivorous foods including mysis shrimp, copepods, and frozen bloodworms. They are nocturnal feeders and may require food sinking into caves or shaded areas rather than competing in open water.

Difficulty and care for the Moluccan Cardinalfish

Moluccan Cardinalfish require moderate care due to their nocturnal nature and specific feeding requirements. They are generally hardy once acclimated but need proper shelter and consistent small food offerings to thrive in captivity.

Common health issues

Starvation if not fed appropriately for nocturnal behavior, parasitic infections, fin rot in poor water conditions

Origin and habitat

Western Pacific, primarily the Molucca Islands and surrounding Indo-Pacific region including Indonesia and the Philippines.
