However, there are many varieties of arowana, and how to distinguish them becomes a difficult problem for novices. This article combines hot discussions on the Internet in the past 10 days to provide you with a systematic differentiation guide from variety classification, appearance characteristics to market value.

3. Recent market hot trends (data in the past 10 days)
| hot topics | focus of discussion | Platform popularity index |
|---|---|---|
| The appearance of the "Blood Red Dragon" is controversial | Does hair color depend on color-enhancing feed? | Douyin/Tieba 82,000 |
| New grading standard for over-back Golden Dragon | Pearl scale brightness detection method | Zhihu/Bilibili 65,000 |
| Breakthrough in artificial reproduction technology | F3 generation red dragon hair color stability | WeChat public account 48,000 |
4. Guide to purchasing pitfall avoidance
1. Certificate verification:Regular Arowana should be equipped with a chip certificate (such as CITES certification). The recent exposure of the "Target Fish" incident reminds consumers to verify the chip number on the official website.
2. Identification of juvenile fish:For juvenile red dragons, you need to observe the outline of the erythema on the gill cover. For juvenile golden dragons, focus on checking whether the gold lines in the fifth row of scales are coherent.
3. Feeding costs:A recent survey by aquarists shows that the average annual cost of raising golden arowana is about 2,000 yuan (including water, electricity and feed). The cost of red arowana is 30% higher because it requires special lighting.
5. Expert advice
The "Guidelines for Quality Assessment of Ornamental Arowana" recently released by the Chinese Academy of Fishery Sciences emphasizes that high-quality Arowana should have "three symmetries" (symmetrical arrangement of body shape, fin rays, and scales) and "two smoothnesses" (smooth swimming posture and smooth transition of body color). It is recommended that novices start raising silver dragons or green arowanas, and then upgrade to different species after gaining experience.
Through the above systematic differentiation method, combined with market dynamics and professional standards, players can more accurately identify the variety and quality of arowana. It is worth noting that the "Arowana Color Measurement APP" that has become popular on social media recently lacks scientific basis, and it is recommended to rely on physical observation.
