It is impossible for the goldfish to understand what the owner says. At present, no animal can understand human language. The reason why we can see some animals acting according to the instructions given by human beings is also the result of training through conditioned reflex. Goldfish can also be trained by reflex, but few can give instructions by sound like other mammals.
1, often feeding: want to let goldfish recognize the Lord, must often give it feeding, feeding 1-2 times a day, feeding must be timed and quantitative, so that goldfish form a habit, a long time, goldfish will not feed people feel strange, but also to the time will take the initiative to close. This completes the first step.
2. Proper training: When the goldfish is already familiar with feeding, it is necessary to start training it. The training method is also very simple. Just put your fingers close to the fish tank. If the fish is close, you will feed it. In this way, you can train the reflex, and try to make it swim in the direction of the finger swing.
3, your persistence: training must be adhered to, a long time will be effective, if only do it irregularly, the fish can not form a reflex. And even if the fish has been able to interact, but also to give it a reward, otherwise a long time the fish will forget.
