1. How to raise

arowana 1. Water temperature: arowana is a tropical fish, so it likes a little higher water temperature. Breeders can control the water temperature between 24-26 degrees, and try to avoid the temperature difference between morning and evening, so that they can grow healthily.

2. Water quality: Manlongyu likes old water. It can survive well when the PH value is between 5.5 and 8.5 and the hardness is between 5 and 8. They do not require high water quality, but they need to change water regularly, and the amount of water changed each time can be controlled at one third.

3. Feeding: Manlongyu has a mixed diet. It can eat some live baits such as wigglers, filarial nematodes, tubificidae, shrimp, water fleas, etc. It can also eat special dried fish food for Manlongyu. It can also eat some minced meat of fish and shrimp, and even small fish that have just died. Manlong fish should be fed regularly and quantitatively, preferably 1-2 times a day, and the amount of each feeding should be finished within 5 minutes. Manlong fish should not be fed frequently, otherwise they are easy to eat too much, leading to indigestion. Before

breeding, the male fish will spit bubbles in the crevices of aquatic plants to build a nest. After building the nest, he will keep chasing the female fish and mating. After mating, the female fish will lay eggs. The male fish will put the fertilized eggs into the nest with his mouth and protect the eggs until they hatch. Female fish can be fished out directly after spawning, because the female fish may destroy the nest or eat the fertilized eggs. Males can wait for the eggs to hatch before they are fished out.
