Walrus fish usually develop full color when they are 18-22 months old, and will mature in all aspects in 2 years. In terms of size, a 1.5-meter fish tank at home can only grow walrus fish to about 1 meter at most. Walrus fish grow rapidly. Foreign magazines recommend that the aquarium for raising walrus fish should be 4.5 meters long, 1.5 meters wide and 1.5 meters high. Therefore, walrus fish can only be kept in large aquariums. When placing walrus fish in a fish tank, it is necessary to ensure that there is enough breeding space and a wide range of activities for the fish. Judging from this growth rate, when it is still a juvenile fish, it is possible to keep it in a mixed culture with a red arowana that is at least as large as an adult fish. If the size difference is too big, it is not recommended to keep it in a mixed culture.
Although in terms of living habits, walrus fish and red arowana are both tropical fish, they like slightly acidic water quality, and the suitable water temperature and pH value are also the same, but walrus fish are still relatively ferocious, and their body shapes are very different. , the red arowana is too vulnerable.
