The normal growth of the Australian star dragon, in the adult body length can reach more than 50 cm. But if the tank in which they are raised is too small or the environmental conditions are too poor, their growth and development will be problematic. Some breeders reported that the Australian star dragon can only grow to 40 cm or even 35 cm, which may be caused by the small tank or the wrong way of breeding.
Although the Australian Astronotus is not very large in size among arowana, they can also grow to 50 cm. Therefore, when breeding, we should use a larger tank. The length of the fish tank should be at least 1.2m, and if conditions permit, it is more recommended to use a large fish tank with a length of more than 1.5m. The width of the fish tank should be more than 60cm and the height should be more than 80cm. So that they can have enough space to move around and grow better.
The theoretical life span of the Australian star point dragon is about 30-40 years, but when it is actually bred, it can only live about 18 years. If the breeding environment is poor, they may not live to 18 years old. Their growth and development rate is not very fast, female fish to grow more than 6 years, male fish to grow more than 5 years, can have reproductive capacity.
