Beautiful hard bone tongue fish, also known as Asian Dragonfish or Golden Dragonfish. It belongs to an ancient primitive freshwater fish species. The adult fish is 50-65 centimeters long, with a maximum length of up to 102 centimeters, and can live for several decades. It is fierce in temperament and mainly preys on live fish, shrimp, aquatic insects, and frogs. When young, it has a blue color with a green base and a light red band with golden fine borders. As it grows, the light-colored scale borders will change to golden yellow, and the golden-yellow scale bars on the blue or green base will extend to the fifth row of scales, crossing the entire dark green back. The difference between the red-finned and golden varieties, apart from the scales, lies in the color of the fins and anal fins. The upper half of the back and caudal fin should appear dark blue. Adult fish keep the eggs in their mouths until they hatch into fry, hence the nickname "Dragon Spits Pearls". The beautiful hard bone tongue fish is named "Dragonfish" due to its large and elongated body, covered with large and orderly arranged shining scales that emit a dazzling light. It has a large mouth and two barbels on the corner of its lips. When swimming, it has a calm and leisurely appearance, resembling the "dragon" in mythology.

1. Fin Rot
Discovering "white hairs" on the fish body, the disease progresses, the affected muscles rot, the appetite decreases, and eventually death occurs. This disease can occur throughout the year.
Treatment: A. Soak the diseased fish in a 3% saline solution once a day for 5-10 minutes. B. Soak the diseased fish in a solution of 2ppm potassium permanganate and 5% saline solution for 20-30 minutes, once a day. C. Rinse the diseased fish in a solution of 1-2ppm malachite green for 20-30 minutes, twice a day. D. Soak the diseased fish in a 5ppm furan solution until cured.
2. Pinecone Disease
The scales of the diseased fish stand upright like pinecones.
Treatment: A. Bathe the diseased fish in a solution of 1/100,000 units of tetracycline once a day for one hour. B. Mix a 2% sodium chloride solution with a 3% sodium bicarbonate solution, and bathe the diseased fish twice a day for 10 minutes each time. C. Add 0.5g chloramphenicol per 40kg of water for bathing.
3. Fluke Disease
After the fish is infected, it swims rapidly in the water tank.
Treatment: Place the diseased fish in a formalin solution, 1 ICC of formalin in 4kg of water. After soaking for one to twenty seconds, immediately remove the fish and put it back into the original water tank. Repeat twice a day for 2-3 days to cure.
4. Cold
The fish remains still, floating on the surface of the water, with dull skin and fins.
Treatment: Maintain a constant water temperature and soak the diseased fish in a solution of baking soda or 1% saline solution to increase light exposure and gradually restore health.
5. Fish Lice Disease
The skin of the diseased fish becomes inflamed and ulcers appear. When the parasites adhere to the fish's body, the fish will rub against the glass and other objects.
Treatment: Place the diseased fish in a 1.0-1.5% saline solution to remove the parasites after 2-3 days.
6. White Spot Disease
In the early stage, there are individual small white spots on the fins and body, with appetite and no significant change in spirit; in the middle stage, white spots are everywhere, with no appetite, no activity, itching everywhere, and the color darkens; in the late stage, white spots cover the whole body, the fish float on the water surface or sink to the bottom of the tank. The fish becomes weak, sways from side to side, the mucous membranes on the body surface increase, breathing becomes difficult, and it dies of suffocation.
Treatment: This disease requires comprehensive treatment. Medication alone is not very effective, and strengthening breeding management is important. First, stop feeding for 4-5 days to reduce pollution; at the same time, maintain a constant water temperature, and raising it by 2-3°C higher than the original temperature is preferable. Medication can be applied appropriately in the absence of aquatic plants, as they quickly die when exposed to various drugs.
7. Black Spot Disease
"Black spots" grow on the fish body, appearing grayish-white, with fungal filaments entangling and adhering to the cells and tissues of wounds, causing tissue necrosis. At the same time, the diseased fish's appetite decreases, and eventually death occurs.
Treatment: Placing a small amount of salt in the aquarium where newly introduced fish are kept can inhibit the occurrence of fin rot. When adding live feed, pay attention to cleanliness and disinfection. Keep the water clean to isolate the growth of fungi. In general, this disease can be prevented.
1. Water Temperature: Dragonfish is a tropical fish and prefers slightly higher water temperatures. When artificially cultivating them, the water temperature should be maintained between 28-30℃. If possible, it is best to install a heating rod to keep the water temperature constant.
2. Water Quality: Dragonfish prefer slightly acidic water, so it is best for breeders to adjust the pH value to between 6.5-7.5. They prefer clean and refreshing water, so breeders should ideally change the water every 3-5 days, with each water change being approximately one-fourth of the total water volume.
3. Adequate Space: Dragonfish have a large body size, so breeders need to ensure that they have ample living space during the breeding process. This will allow the dragonfish to grow and develop better.
4. Proper Feeding: The feeding frequency for dragonfish varies depending on their growth stage and water temperature. Breeders need to determine the feeding frequency based on the actual circumstances of the fish and their feeding behavior.
