Sometimes the environment may change too much, the water quality is unstable, and the bait is not suitable, which will lead to not eating for a long time.
To solve this problem, arowana must be watered after it is brought here, that is, the water in the fish bag is mixed with the water in the fish tank, so that arowana can easily adapt to the water quality in the fish tank.
Extended data:
Beautiful bony tongue fish (scientific name: Scleropages formosus): also known as arowana and arowana. It is an ancient primitive freshwater fish. Rivers and lakes native to Malaysia, Indonesia and Sumatra.
Adult fish are 40-50 cm long and have a life span of several decades. Fierce temperament, mainly hunting live fish and shrimp, aquatic insects, frogs and so on. Parent fish keep their eggs in their mouths until they hatch, so they are commonly called "dragon spit beads".
Since the middle of the 20th century, it has developed into an ornamental fish. It attracts a lot of attention, because its shiny metal paste is like armor, and its bright colors (gold, red, etc. ) and dignified manner. Its value has risen to tens of thousands of yuan, making it one of the most precious ornamental fish, including Jinlong, Honglong and Qinglong.
The survival of arowana needs weak acid to neutral water quality, and the hardness needs soft water. The pH value is between 6.5 and 7.5, and the DH value is 3- 12. The water temperature is 24-28 degrees Celsius. The nitrite content and chlorine content are preferably zero.
Precautions for sodium dihydrogen phosphate: the pH value should not be adjusted to more than 0.5- 1pH every day, and violent oscillation will lead to the death of arowana. It is suggested that proper aeration and oxygenation can stabilize pH value.
