Under natural conditions, their body length can be more than 1m.

If cultured in a large enough tank or aquarium, its body length can be almost 80cm.

Bred in an aquarium that is about 1m long, it can only grow to about 60cm, but not much longer.

They also have a longer lifespan.

Long-lived individuals can live for about 50 years, and when bred in captivity they usually live for about 20 years.

I. How big can the red dragonfish grow The red dragonfish is a relatively large tropical fish.

In natural conditions, their body length can be more than 1 m.

Artificial breeding, how long they can grow with the size of the tank.

In a large enough tank or aquarium, it can grow to about 80cm.

Breeding in an aquarium that is about 1m in length, it can only grow to about 60cm in length, but not much longer.

Two, the red dragonfish life expectancy is how long the red dragonfish life expectancy is very long.

In the wild, if the living environment is suitable enough, they can live about 50 years.

And in captivity, their lifespan is about 20 years.

If raised well, they can live for 40-50 years.

So, if you can provide a more suitable growing environment for red dragonfish, you can make them live longer.

Three, the red dragonfish how to raise live longer 1, water temperature: want to let the red dragonfish live longer, must control to breeding water temperature.

The water temperature should be maintained between 24-28 ℃, too high or too low are unfavorable to their growth.

When changing the water, special care should be taken not to make big changes in the water temperature.

So it's best to bask in the sun before each water change, and only change about one-third of the water at each change.

2, water quality: whether the water quality is qualified will also affect their growth status and life expectancy.

When breeding, you should use weakly acidic water with PH between 6-7.

In order to ensure that the water quality is always clean, you also need to change the water every seven days or so.
