Dascyllus auripinnis ( lat . "Aureus" = golden; "pinna" = fin) is a kind from the family of damselfish (Pomacentridae). The fish live in the central Pacific near the Phoenix Islands , the Line Islands and the Cook Islands . There they replace the closely related three-point Prussian fish ( Dascyllus trimaculatus ).
features
Dascyllus auripinnis becomes 11.5 centimeters long. The body height is very high with a ratio of 1 / 1.5-1.65 (body height / body length). The fish are colored gray-blue on the back and sides, the ventral side, ventral, anal and caudal fins are orange-yellow with black edges. There is a small white spot on the middle of the flank above the sideline. The black to dark brown edges of the scales result in a net pattern in fish that are not too black. The caudal fin is indented. Along the lateral line has dascyllus auripinnis 18 till 19 shed. The number of gill trap processes is 24 to 29.
- Fin formula : dorsal XII / 14–16, anal II / 14–15, caudal 8 + 7.
- Branchiostegal rays : 6
- Vertebra 26.
Way of life
The fish live in the coral reefs around the atolls of their home islands. Like other Preussen fish feeds dascyllus auripinnis of copepods , other small planktonic crustaceans and possibly also of algae. Like all damselfish, the fish are substrate spawners and stick their spawn to the wall in a cave or hidden niche. The male guards and cleans the spawn.
