is used to raise the colorful angelfish? The size of the colorful angelfish is medium, and there is no special requirement for the choice of the tank. Under the condition of artificial feeding, the appropriate type of tank can be selected according to the number of fish raised and the size of the fish body. Under
normal circumstances, a fish with a body length of 1 cm needs at least 1 liter of water for maintenance. At this time, the selected fish tank is too large or too small, which is not conducive to its growth. For a fish with a size of 4-12 cm, a tank with a length, width and height of 120 * 50 * 45 cm can be selected. For the breeding of fish, it is best to use a tank with a length, width and height of 50 * 50 * 45 cm. The number of fish that can be stocked in the
tank can be calculated by the formula: the volume of the tank (liter) ÷ the body length of the fish (cm) = the number of tails.
the colorful angelfish? The colorful angelfish has a higher requirement for water quality, so it is necessary to install a filter in the fish tank when maintaining it. The most commonly used filters are generally top filters, barrel filters, sponge filters, external filters, etc. Filter materials commonly used in
filters generally include white filter cotton, activated carbon, ceramic ring and sponge filter cotton. Because the sponge filter cotton is divided into a wall-attached type sponge filter and a vertical type sponge filter, the sponge filter cotton has small water yield and strong capability of culturing and digesting bacteria, and is very suitable for a fish tank with small water yield for the lives of young fish, seed fish and the like.
