How to distinguish between the cross-backed Arowana and the red-tailed Arowana
Arowana (Definite introduction)

The dispute between the cross-backed golden dragon and the red-tailed golden dragon has always been the most objectionable place in the hearts of aquarists for a long time. One row more and one row less Identification is often dazzling. When choosing a cross-backed golden dragon, the most terrifying thing is to spend a lot of money to buy back a red-tailed golden dragon. In this case, how to learn from the youth of the arowana? How can we judge whether a golden dragon fish species is an over-back or a red-tailed golden dragon after it has grown for a long time? This question should be the topic that all arowana enthusiasts want to know the most. The difference between over-back and red-tailed golden dragons cannot only be distinguished by beady scales. There are actually four indicators for identifying over-back golden dragons: < br> 1. Body shape: Especially the head shape. There is a difference between the over-the-back cannon head and the red-tailed cannon head. You may wish to take a closer look.
2. Scale color: Whether it is bronze gold or light gold, the color of regional purebred red-tailed blond hair is very different from the goose gold color on the back.
3. Tail scales: A tail scale that goes over the back will cover the entire tail at birth, instead of the scales on the upper half of the tail being black like a red tail. You may wish to turn it over with your hands. Check out the Arowana magazine and compare the tail scales.
4. The golden thread behind the eyes: The golden thread behind the eyes will appear when it is about 10cm.
