To raise walrus fish, you must first prepare an aquarium suitable for the healthy growth of walrus fish based on its body shape, characteristics and living habits. box.
Walrus fish generally develop full color when they are 18-22 months old. In 2 years, you will develop maturity in all aspects. In terms of body size, a 1.5-meter fish tank at home can only support walrus fish until they grow to about 1 meter. Walrus fish grow rapidly.

If the water level in the tank is low, protective measures must be taken on the top of the tank to prevent it from popping out and causing unnecessary damage.
In terms of living habits, walrus fish are hot-weather fish, they like weakly acidic water quality, and their requirements for water quality are not very strict. , the suitable water temperature is between 24 degrees and 29 degrees. However, judging from everyone’s breeding experience over the years, as long as the walrus fish is suitable, the water temperature can be appropriately increased to between 22 degrees and 31 degrees. As the direct relative of the arowana, the walrus fish requires stability in the water temperature and cannot change drastically.
Arapaima, a kind of walrus fish, is a carnivorous fish and must be fed from juvenile to adult fish. Animal bait is best used to feed small moving fish. Animal offal can easily damage the digestive system and cannot be fed. The artificial synergistic feed for feeding is mostly shrimp feed (floating).
