Banggai Cardinalfish [Diet, Characteristics, Habitat, Etc.]

Banggai Cardinalfish

Banggai Cardinalfish is a small, tropical fish that belongs to the Apogonidae family. It’s the only one in its genus and popular for aquariums.

While it is bred in captivity, many are caught in the wild which has led to its endangered status.

Human impact on its environment and diseases like Iridovirus also threaten this species.

Banggai Cardinalfish is found near jetties, with silty sand bottoms and seagrass called Enhalus acoroides.

This fish lives with long-spined sea urchins called Diadema setosum.

Groups of 2 to 60 fish hover above the urchins, especially younger ones that stay closer for protection.

When threatened, Banggai Cardinalfish hides among the spines.

Young Banggai Cardinalfish also use anemones as protection.

Banggai Cardinalfish primarily feed on small crustaceans at night. This species is safe for reefs.
