Goldfish can see the master. It should be noted that fish do not necessarily identify people through appearance, but also through sound and other information, so it is not very accurate to see clearly, but when close, fish can often know, and there will be a series of behaviors, such as the performance of very active, or like the direction of people swimming, feeding will also be close to the water surface and so on.
1, sound swimming: goldfish to recognize the owner of a major performance is when they hear the owner close, will swim in the direction of the sound. Generally, fish seen in the wild will swim away immediately once they find people close to them, instead of actively approaching them. And domestic fish, if it is not familiar with the people close, the fish will not respond.
2. Active performance: When the owner is near the goldfish, the goldfish tends to be very active and swim very fast. This performance is mainly due to the fact that the fish is often fed at ordinary times, which causes the fish to form a reflex and swim quickly in the fish tank to look for food. Therefore, the performance is very excited, not out of nervousness.
3. Concentrate on the surface of the water: In addition to being very active, some fish will also concentrate on the surface of the water. This is also their performance of waiting for feeding. However, they should also pay attention to whether there is a floating head. If there is, they should be oxygenated in time.
