1, the space needed to raise hexagonal dinosaurs should not be too small, and hexagonal dinosaurs need 45 cm of living space.

2. The water temperature of feeding hexagonal dinosaurs should not be too high, and the water temperature exceeding 25 degrees is not conducive to their growth. Hexagonal arowana is a kind of salamander, and the water temperature suitable for their life is preferably between 16 ~ 20 degrees, which is quite demanding.

3. Hexagonal arowana should not be mixed. They eat a lot, and when they have nothing to eat, they will bite their own fish or other fish. When Hexagonal Arowana is in larval stage, they have a strong tendency to devour each other.

Characteristics of hexagonal dinosaurs:

1, hexagonal dinosaurs' eyesight is not very good, so they mainly rely on their sense of smell to find food, and when they eat, they will open their mouths and suck hard. Therefore, pebbles (not smaller than their mouths) should not be scattered in the culture tank to avoid being inhaled by them, damaging the digestive tract and even causing death.

2, because of poor eyesight, often eat the same kind, causing harm. At the same time, they have no scales to protect themselves. The red gill filaments are very similar to red nematodes, so they are easily bitten by other fish and turtles. So it's best to keep a hexagonal dinosaur alone or change a big fish tank.

3. The original environmental temperature of the hexagonal dinosaur is only 14~20℃, so it is best to keep the water temperature in the fish tank low.

4. Hexagonal dinosaurs ate a lot, so they must be fed enough food.
