Grooming a Red Arowana involves maintaining the cleanliness and health of their aquatic environment. Here are some tips:

1. *Tank Setup:* Provide a spacious tank with proper filtration and water quality. Arowanas are sensitive to poor water conditions.

2. *Water Parameters:* Maintain a pH level between 6.5 to 7.5, a temperature between 75-82°F (24-28°C), and ensure good water circulation.

3. *Diet:* Feed them a balanced diet of high-quality pellets, live or frozen foods like shrimp and fish. A varied diet helps maintain their vibrant color.

4. *Tank Decor:* Add suitable hiding spots and plants. Arowanas appreciate some natural elements in their habitat.

5. *Regular Water Changes:* Perform regular water changes to remove waste and maintain water quality. Aim for 10-20% weekly changes.

6. *Tank Mates:* Choose tank mates carefully, as Arowanas can be aggressive. Avoid species that may nip at their fins.

7. *Observation:* Keep an eye on your Arowana for any signs of illness or stress, such as changes in behavior, appetite, or color.

8. *Handling:* Minimize handling, as it can stress the fish. Use a soft net when necessary.

9. *Quarantine:* Quarantine new fish before introducing them to the main tank to prevent the spread of diseases.

Remember that Red Arowanas are a high-maintenance species, and their specific needs must be met to ensure their well-being and vibrant coloration.
