Introduction of fire unicorn Lohan
The first time I saw this name was on the old version of the horn-headed and meat-headed pearls. Generally speaking, if the whole body is more than 70% red, it can be called "fire unicorn".
What's unique about Lohan fish? If you carefully observe an arhat fish, you will unconsciously be captured by its humanized form. The rosy cheeks and towering forehead symbolize happiness and longevity, and the "ink spot scale" with different shapes on both sides has a more important role in promoting wealth in Feng Shui.
Selecting Lohan: You can refer to foreign grading standards to select Lohan. Generally, the body color is dark, with only 1-2 spots, and the longer body can only be classified as Grade C (Grade 3); With the middle part of the body as the boundary, the spots on the back are not more than the middle part, but the body surface is bright and there are some twinkling stars on the scales, which can be classified as Grade B (Grade II); The mottled arrangement extends from the middle to the vicinity of the head, and the lower body surface behind the gills tends to be red, and the twinkling stars on the body surface are widely distributed. Those clearly marked shall be rated as Grade A (Grade I); There are also strange features, such as text spots, strange colors, dotted features, gorgeous features and so on. , all qualified as special grade. (Note: Now the standard has been changed)
Lohan: Try to use a larger water tank (above 90 cm). Lohan is more than 20cm in size and belongs to medium and large cichlids. Its territorial concept is very strong, and it is recommended to keep it in an aquarium alone. In addition, the size of space will also affect the growth speed and shape of arhat, so it is best to choose an aquarium with a height of 1m when raising it, so as not to limit the growth of fish. Taking black or blue as the background of the aquarium will help Lohan to present the most beautiful body color, help the fish grow into larger individuals and promote a better head shape. Lohan grows fast and has an excellent appetite, so there is relatively more excrement. An effective filtration system can ensure the cleanliness of water quality and greatly reduce the occurrence of fish diseases. It is best to add some oxygen-increasing equipment (such as gas sticks and biochemical cotton tubes). ) to improve the dissolved oxygen in water and make fish more energetic.
According to personal preference, bottom sand can be added to the bottom of the tank to simulate an ecological environment close to nature, which will make the fish feel more at ease, stimulate the fish to estrus and increase the head shape. Arhat likes neutral or slightly acidic water. It is best to use river sand with a particle size of 0.5- 1cm as bottom sand to keep the water quality neutral, and the bottom sand can be spread to a thickness of about 5cm. The layout of the water tank should avoid using heavy wood or coarse stones to prevent fish from accidentally injuring the scales.
Aquarium must have fluorescent lamp, which reflects the beauty of fish and is pleasing to the eye. Most tropical fish are kept in outdoor small ponds when they are in artificial farms. Due to long-term exposure to the sun, their colors are very bright. When aquarium enthusiasts bring tropical fish home to raise them, if they are not provided with proper light, their body color will gradually decline. It is suggested that the daily light can be controlled at about 10 hour, which will add points to the health of fish and the performance of color selection.
In order to ensure the smooth growth of fish, a set of safe thermal insulation equipment (such as thermal insulation rods or electronic thermostats) should be prepared.
The water thermometer is convenient for everyone to accurately monitor the water temperature at any time.
Water quality: Before tap water is used, it should be exposed to the air to remove chlorides and harmful substances from the water.
Higher acidity will affect the growth rate of fish, and it is ideal to keep the PH value at 6.8-7 degrees.
Too low water temperature will affect the metabolism of fish, and it is ideal to keep it at 26-28 degrees Celsius.
Feeding: Lohan grows rapidly and needs more food. Basically, you need to feed it two to five times a day. The quantity should be controlled within five minutes at a time, so as to avoid eating leftovers, so as not to affect the water quality. Remember to eat less and more meals to avoid gastroenteritis. Lohan are not picky eaters, they are willing to accept live bait (earthworms, small fish, etc. ), frozen bait (frozen shrimp, frozen insects, etc. ) and feed (strips and granules). Generally speaking, it is suggested that feeding frozen blood worms, supplemented by frozen shrimp and colored bait, can achieve ideal results and is very convenient.
Disease: Lohan is strong. As long as the water quality is good, he seldom gets sick.
