The Banggai cardinalfish (Pterapogon kauderni) is a small tropical marine fish found around the Banggai Islands in Indonesia. It is often found associated with the seagrass Enhalus acoroides and the long spined sea urchin Diadema setosum. This fish, popular in the aquarium trade, grows up to 8 cm (3 in) total length and has an elongated second dorsal fin and anal fin, as well as a tasseled first dorsal fin. Its caudal fin is deeply forked. Its contrasting pattern of black and light bars with white spots makes it very recognizable.
These fish have been successfully bred in captivity. The male broods the eggs and later the fry in his mouth cavity. The male does not eat at this time and will hold the brood of around 25 fry for 4-5 weeks. Juveniles use sea urchins and sea anemones for protection. Fry can then be raised on brine shrimp nauplii enriched with marine lipid supplements.
Collection for the aquarium trade has threatened this species with extinction, increasing the demand for captive-bred specimens. This species will be considered for addition to CITES (Convention on International Trade of Endangered Species) Appendix II in June 2007.
