? Kissing fish are tropical fish. They mainly live in rivers, lakes or ponds in tropical areas. They belong to standard tropical fish. Kissing fish can also grow in the wild with a body length of 17-30 cm, so it is edible in its origin. But captive fish can only reach 3-5 centimeters in length, and they fight in a different way from other fish. When they fight, they will kiss each other until one of them gives up first. But many people think that the meaning of kissing fish is good, so they are loved by many fish friends. Kissing fish are gentle and slow to swim, so they are more suitable for polyculture with other tropical fish.
? Kissing fish do not need high oxygen demand, and they are small in size, oxygen consumption is not high, so in general, they do not need oxygen. If there are a large number of fish in the fish tank, or if there are fish with high oxygen consumption in the fish tank, the breeder needs to oxygenate them. Because high density will reduce the dissolved oxygen in the water, kissing fish will suffer from discomfort after hypoxia. Moreover, in summer, when the temperature is high, the breeder also needs oxygen, because the high temperature will also reduce the dissolved oxygen in the water. In other seasons, as long as the feeding density is not high, oxygen can not be used.
