The Banggai Cardinalfish is only found in the oceans around the Banggai Islands of Indonesia. It prefers shallow coral reefs, seagrass beds, and open areas of sand and rubble. It likes calm habitats.

It is diurnal, active during the day. It is an opportunistic feeder. Its diet includes planktonic organisms. Its predators include lionfish, grouper, stonefish, and moray eels.

It swims in small schools of about 9 individuals within larger schools of up to 500 individuals.

The female Banggai Cardinalfish lays about 90 eggs on the ocean floor. The male looks after the eggs and the newly-hatched fish in his mouth. When the young fish become larger, the male parent spits them out of his mouth. He is called paternal mouthbrooder.

The average lifespan of the Banggai Cardinalfish is 1-2 years.
