The first is to create a living environment for freshwater tropical fish. Tropical and subtropical geography and climatic conditions make tropical fish live in weak acidic soft water with sufficient sunshine, high water temperature, small temperature difference, and rich natural food. Therefore, their growth, development and reproduction are closely related to water quality and water ecological conditions. In artificial rearing, it is not possible to have the same conditions as those in the homeland of tropical fish, but they must be provided with basic living conditions that can be adapted, including water temperature, hardness of water, and pH of water. 1 Water temperature conditions and adjustment methods Tropical fish is a narrow temperature fish. It has strict requirements on water temperature and is particularly sensitive to changes in water temperature. The water temperature that can be adapted is 20-30 degrees. It is beyond the upper or lower limit of this range and it has life for most tropical fish. Danger - If the water temperature drops below 20 degrees Celsius, the tropical fish will become sick or die; although the water temperature reaches 20 degrees, but if the long-term low, it will affect their appetite and growth; day and night temperature difference is too large, such as more than 5 degrees, also Can cause them discomfort, over time can lead to death. There are generally two methods for regulating the temperature of fish-breeding water: one is to directly increase the temperature of the water in the aquarium, and the other is to increase the water temperature indirectly by increasing the indoor temperature. 2 water hardness and adjustment methods Most tropical fish require living and breeding in soft water and low hardness water. The hardness of water is mainly determined by the amount of calcium and magnesium salts contained in the water. 8 degrees is soft water, 8-14 degrees is low hardness water, and 20-30 degrees is hard water. The general rainwater and snow water are soft water; in southern China, the red soil in South China has more soil quality, and the hardness of the water in the rainforest belt river is low, mostly soft water. With less rainfall in the north, the soil contains high amounts of saline and alkaline water, and the water hardness is also high. Tropical fish require less water hardness than water temperature, and water with higher hardness can adapt. However, water or soft water with low hardness is required for reproduction. Tap water is a common source of water for farming tropical fish. The easiest way to determine its softness and hardness is to boil it and look at the scale in the kettle. It is hard water and soft water. 3 Water pH and its regulation method The pH of water refers to the concentration of hydrogen ions contained in the water. The pH of the water can be measured with a pH tester or an analyzer. Refer to the instructions for use. 4 Feed Selection and Feeding Methods Most tropical fish are carnivorous, few are omnivorous, and very few are herbivorous. Carnivorous fish are divided into ferocious and mild. The ferocious mouth is large and fierce. He likes to eat large pieces of food such as small fish, shrimps and clams, such as Texas leopard fish and arowana. The mild fish is also small, and he likes eating small animals such as leeches and chironomid larvae. . When feeding, fish should be fed selectively for feeding. The selected food must be fresh. The natural food is preferably fresh and frozen. The artificial diet cannot be mildewed. In addition, in order to avoid lack of nutrition, as long as fish can accept, the choice of feed should be as diverse as possible, and the variety of feed should always change. After choosing the right bait, we must also grasp the correct feeding method to be able to make it long and fast. Feeding the tropical fish also needs to determine the amount of feed. The control method for feeding the feed is very simple, that is, feed it little by little. At the beginning, the fish will snatch food, and when the fish catch food is not obvious, it can be stopped. If you feed too much at a time and the fish can't finish, it will remain in the water and affect the water quality. In general, feeding 1-2 times a day is all right. It is best to feed at the same time. If a fish family wants to raise several tropical fish at the same time, it can be fed twice a day, sooner or later. Tropical fish can only have a good appetite if grown in a suitable environment. Therefore, in addition to the delicious food, we must create an environment suitable for their growth. Low dissolved oxygen, inappropriate water temperature, and deterioration of water quality all affect fish appetite.
