(Pterapogon kauderni)
Fish
Pacific Ocean
This small, disc-shaped fish is easily recognized by its tasseled first dorsal fin; long, tapering second dorsal fin; and deeply forked tail, or caudal fin. The Banggai cardinalfish’s colors are striking—bright silver flecks and several bold, black, vertical stripes adorn its gray body.
Hiding comes naturally to these fish—if you can’t spot them, look closely among the tentacles of the anemones.

The range of this cardinalfish is restricted to the Banggai Islands in Indonesia. It is common around jetties and over sandy bottoms with sea grasses.
The Banggai, along with most others in the cardinalfish family, feeds on plankton and small, bottom-dwelling crustaceans.
This species reaches about 3 inches in total length.
Banggai cardinalfish were introduced into the pet trade in the 1990s and are popular in home aquariums. Because of their restricted range and shallow habitat, they are in danger of exploitation and over-collection. Some experts fear this could lead to extinction.
Humans pose the biggest threat to Banggai cardinalfish, as the fish are popular among aquarium hobbyists. These fish also fall prey to several natural predators, especially as juveniles, when they are plucked from the spines of sea urchins by hungry passers-by.
