Answer:

1、What is the scientific name for the arowana fish?

- The scientific name for the arowana fish is *Osteoglossum bicirrhosum*. This species is commonly known as the Asian arowana or simply arowana.

2、How large can an adult arowana grow?

- An adult arowana can grow quite large, with some individuals reaching lengths of up to 40 inches (1 meter) or more. Their size can vary depending on the subspecies and the quality of care they receive.

3、What are the typical water conditions required to keep an arowana in captivity?

- Arowanas require very specific water conditions to thrive in captivity. They need warm water, typically between 75-82°F (24-28°C), and a pH level ranging from 6.0 to 7.5. The water should be clean and well-aerated, often requiring a powerful filtration system due to their high metabolic rate and large bioload.

4、Are there any specific care requirements for breeding arowanas?

- Breeding arowanas can be challenging and requires careful attention to several factors. Firstly, both male and female arowanas must be mature and healthy. The breeding tank should mimic natural conditions, including appropriate temperature and water quality. Additionally, providing a suitable spawning substrate and ensuring privacy from disturbances can increase the chances of successful breeding. After spawning, the fry require specialized care, including feeding them appropriate food like infusoria or specially prepared fry food.

5、Can arowanas change their color, and if so, under what circumstances?

- Yes, arowanas can change their color, although the extent and frequency of these changes can vary.
