Tropical fish are creatures with high requirements for water quality, and whether the water quality meets the survival requirements of tropical fish is the key to keep tropical fish healthy. First of all, the water temperature should be kept between 24℃ and 28℃, and the indexes such as salinity, pH value, hardness and oxygen content in the water should also be kept in a suitable range. Generally speaking, water with neutral pH, low salinity, moderate hardness and sufficient oxygen is the best environment for tropical fish to survive.
2, light requirements
Appropriate light characteristics are also essential for the survival of waterfall fish, and light directly affects the growth, color and immunity of tropical fish. The adequacy of light not only affects the color of tropical fish, but also affects its normal growth and behavior. In addition, sufficient light can also improve the transparency of water, so that tropical fish can perceive the food and obstacles they are foraging in time, and ensure normal behavior and healthy growth.
3, water flow and oxygen requirements
Water flow and oxygen content are necessary conditions for tropical fish to exercise fully and breathe normally. The current and its intensity directly affect the behavior of tropical fish, such as full movement and spawning. Appropriate current speed can make fish swim more freely. In addition, tropical fish are also very sensitive to oxygen in water. Sufficient oxygen can increase the saturation of water, prevent harmful gases from being produced in water, allow fish to breathe fully and create a suitable living environment.
4, waterscape requirements
Waterscape layout is also a necessity to maintain the survival of tropical fish. Medium aquatic plants and dwarf plants have the function of gathering and purifying water quality. Creating a natural and comfortable living environment can make tropical fish close to nature and reduce stress. However, the growth of aquatic plants also needs a certain amount of light, and the growth of grass should be trimmed frequently and timely to create a fresh and clear living environment.
