The golden or yellow stripe cardinalfish ( Ostorhinchus cyanosoma , syn .: Apogon cyanosoma ) is a schooling fish from the family of cardinalfish (Apogonidae).
It lives in the Red Sea and the Indo-Pacific , from Mozambique to the Ryūkyū Islands and Tonga in shallow water from one to twelve meters deep. During the day it hides between branch-shaped hard corals and sea urchin spines to hunt for zooplankton at dusk .
features
Golden striped cardinalfish grow to a maximum of eight centimeters, but usually stay at six centimeters. Their dorsal fin is clearly separated into a hard and a soft part. It is supported by eight spines and nine soft rays; the anal fin has 2 spines and eight soft rays. The fish are of a silver-blue basic color and show six yellow-orange vertical stripes. The middle stripes end in a reddish point on the caudal fin base.
Reproduction
Like all cardinalfish, the goldstripe cardinalfish are mouthbrooders . The courtship lasts four to five hours. Then the female lays a large, white egg ball in just five seconds, which is immediately taken into the mouth by the male and remains there until the larvae hatch after about eight days. In the aquarium it was observed that the respective females are always close to the males. The hatching larvae are about one millimeter long.
