1. How to choose silver arowana and distinguish between male and female

The following are the methods to distinguish the gender of silver arowana: 1. It is not difficult to distinguish the gender of silver arowana. The main difference is that the pelvic fin of male fish is long and pointed, while the abdomen of female fish is more swollen when sexually mature; 2. A beautiful A-shaped figure can be seen on the gills of female fish, and the arrowhead part is shorter than that of male fish, while the opposite is true for male fish, the A-shaped figure is irregular and the arrowhead part is also longer. Moreover, the entire head of female fish looks smaller than that of male fish. Since male fish have to contain roe, the head is slightly larger. This is the first point; 3. The body size of arowana (total length). Male fish of the same age are longer than female fish, although this is limited by the size of the tank and the environment. However, most families set up a tank of about 100 by 600 by 900. In this case, the growth rate and size of male and female fish will be very different. There is no difference in growth rate from 15cm to 20cm. The growth rate of female fish will slow down significantly from 35cm. It is possible to spawn at around 30cm, and there are also examples of spawning. Let's make it clear here that a fat fish does not mean it is big. Here we are talking about length.

On the contrary, the weight and width continue to increase. In this case, it is very likely that the fish is a female. So here is a reminder for everyone, don't feed too much food to avoid your fish having high blood lipids.

Generally, it inhabits the pools of tributaries and the submerged bushes on the shore. Sometimes silver dragon fish can be found in the water environment with floating grass. Later, it flowed into my country. The breeding of silver dragon fish in the south has been successful. It is one of the main ornamental fish in my country. Silver dragon fish is quite popular in Southeast Asia in Asia due to Feng Shui needs.
