They spawn in July to September, at temperatures of 24 to 29 degrees. Their spawning size measures usually 80 to 90 mm or more in total length. They mate 7 to 10 days prior to spawning. In mating, the pair separate themselves from the school at a corner of the tank in the aquarium and drive off all the fishes coming near. The courtship is mainly expressed by the female at first, and normally a few days before the spawning, the male begins to respond to it. At the spawning, the pair swim side by side firstly, then the male turns himself upsidedown, so that his belly approximately comes in contact with hers. In this way the eggs are layed in a mass and inseminated readily. After a few seconds, the male holds the egg mass, which is still attaching to the genital opening of the female, in his mouth. After the spawing, the male joins the school and shows no more attention to the female. The eggs survived for only two days or less in the aquarium, so the development was not observed.}, pages = {14--17}, title = {クロホシイシモチApogpn notatus (HOUTTUYN) の産卵習性}, volume = {11}, year = {} }
