Behavior

Banggai cardinalfish are peaceful fish species that prefer to live in groups of at least 6 individuals.

They are not aggressive towards other fish, but they can be easily intimidated by larger, more aggressive species.

The Banggai cardinalfish is a carnivorous species that feeds on a variety of small invertebrates, including zooplankton, copepods, and small crustaceans. In captivity, they can be fed a variety of frozen or live foods, including brine shrimp, bloodworms, and mysis shrimp.
