Banggai cardinalfish (Pterapogon kauderni) is a small tropical cardinalfish (familyApogonidae) is very popular used as ornamental fish.
Habitat This species exist only in the Banggai Islands, Indonesia. This species lives in a very limited geographic range of 5500 km ² and with a population of only around 2.4 million only. Banggai cardinalfish is an isolated population and are concentrated in shallow peraiaran on 17 major islands and 10 small islands, the Banggai Islands. A small population is located in Central Sulawesi Luwuk. Additional populations from Lembeh Strait (North Sulawesi), about 400 km north of the original habitat (based on reports from fishermen that perdagangkannya in 2000).
Description This species grows to a maximum length of 8 cm has a special style that contrasts between black and white bright lines. Specific differences that distinguish the other cardinalfish is on the first dorsal fin has pigtails, anal fin and second dorsal fins protruding back, forked caudal fin (very deep branches), has a color pattern consisting of 3 pieces of black lines on the head and body, striking black color on the edge of the beginning of the anal fin and second fin Banggai cardinalfish dorsal.Yang distinguish male and female is larger male oral cavity and was only seen them at incubating their eggs.
Ecology Banggai cardinalfish is the only representative of the family are diurnal. Tropical sea demersal fish that form a stable group consisted of nine individuals in shallow waters (generally 1.5 to 2.5 meters depth). This species inhabits shallow waters with a variety of habitats including coral reefs, seagrass beds, and open areas of sand and rubble bersubstrat, generally in a quiet area sheltered by large islands. This species is often found associated with seagrass of Enhalus acoroides and sea urchin Diadema setosum.Hi This happens on various benthic substrates such as sea urchins, sea anemones, and coral branching; young fish are often most associated with sea anemones, after youth and adults in association with sea urchins and branching corals, star lau, hidrozoa, and sustainer of mangrove roots.
This fish including species of opportunistic eaters all day, unlike other spessies-species of the same family. Composition of diet equal to the size of classes, including plankton and benthic organisms. Copepods is their main food. Copepods also become an important food source for various species such as Lionfish (Pterois), Epinephelus merra, crocodilefish (Cymbacephalus beauforti), moray eel (Echidna nebulosa), stonefish (Synanceia horrida), and sea snakes Laticouda Colubrina.
Banggai cardinalfish is mouthbrooder paternal (male parent who lay eggs). Female parent role in the formation and pair formation, which occurred several hours to several days before the fish spawn. Pairs spawn a few meters from the main group and defend their territory. Egg size Banggai cardinalfish has a diameter of 2.5 mm. These fish have a short life span (approximately 4 years in an area with ideal conditions; 2 years in the wild areas), and the number of eggs a few (50-90 bouts) r though it has the potential spawn several times per year (after the age above 10 months).
